to get on with familiar them to get on with the start without top story. the chinese owner of tiktok has said it will sue the us government over a new law which requires it to sell the video—sharing platform or be banned in america. the company has called the legislation an "extraordinary intrusion on free speech rights". from new york, michelle fleury has more. tiktok is hugely popular in america. 170 million people use the platform to communicate. lawmakers aren't so keen. congress and the biden administration believe the app and its chinese owners bytedance could be a danger to national security. the argument goes that beijing could commandeer it to surveil and manipulate americans. so they've given the company until the day before the next us president takes office — on the 20th of january — to sell or face a ban here in the united states. tiktok, well, it's fighting back, challenging the constitutionality of the new law, arguing in its legalfiling,

for the first time in history, congress has enacted a law that subjects a single named speech platform to a permanent nationwide ban. the company also says that it's not possible legally, technically or commercially to divest within that time frame. part of the challenge is that with a billion users worldwide, a lot of its content is actually available across borders, making it all harder to unpick. the usjustice department declined to comment, but here's what white house press secretary karinejean—pierre had to say when asked about why president biden continues to use tiktok for his political campaign. so as it relates to the campaign, and obviously other congressional members, they have to speak to themselves, the campaign has to speak to it, but we've been very clear — what this law is is not a ban, it is a divestment. tiktok�*s ceo shou zi chew, who appeared with his wife, vivian kao, at the met gala last night, is hoping tiktok�*s other recent first amendment

victories in the us, like blocking the state of montana's bid to ban it, will help it prevail again. outside of the courts, tiktok�*s best hope in a general election year is for donald trump to retake the white house, given that one of mr trump's big backers and a major republican donor, jeff yass, is also a tiktok investor. tiktok will face challenges when proving its case in court. that's according to kirk mcgill, a lawyer at hall estill. one of the primary difficulties that tiktok is going to have is that the principal first amendment issue is the issue of its users�* first amendment rights, as opposed to the company's first amendment rights. and because the statute doesn't seek to ban tiktok, it seeks to require its divestment, that won't ultimately affect the end—users, and they're the ones whose rights are most at issue. and for when it comes to the us government, they need to prove in court that there are national security issues — is that the case? that's precisely right. the difficulty is, the united states government has to balance showing its hand

in court in order to beat tiktok but revealing, potentially, its intelligence sources and methods abroad, which may have greater value, and that's always been the difficulty for the government when it comes to national security cases, is the balance between freedom and security and between disclosing its evidence and hiding and concealing that evidence in order to protect its intelligence activities. so, in essence, the two parties involved — tiktok and the us government — are almost arguing to prove two different things? that's right. it's the classic clash between freedom and security that's existed, arguably, since the magna carta, and it's on show again today with tiktok. the times and the technology may have changed, but the issues are quite the same. yes, so give us a sense, then, of what's at stake for both tiktok and the us government in this case? immediately, tiktok�*s concern is going to be remaining operational while the case goes through litigation. so they will likely seek

what's called a stay, which is to ask that the law be put on hold while the lawsuit proceeds. if they succeed in getting a stay, they could delay the statute going into effect for years, even if they ultimately lose the case. the us government, on the other hand, will seek a quick implementation of the law, effectively requiring the divestment or banning of tiktok before the lawsuit even continues, winning the case before tiktok has a chance to defend itself. the us has revoked some licences that allow american companies to ship goods, like chips, to huawei. last month, the chinese telecom giant launched its first ai—enabled laptop, powered by an intel processor. us officials see huawei as a national security threat and have been trying to hobble its ability to develop the latest technology. apple has unveiled a new artificial intelligence chip in its latest ipad pro. this comes despite sales for the iphone and the ipad falling. ryan reith from market intelligence firm idc said the development was a significant one. this was labelled to everyone as an ipad event and it quickly turned into a chipset event. so, apple announced some excellent ipads that are going to do great in our opinion, but i think the big

storyline here is really the m4 chip announcement, so this is, for those that don't know, this is really sort of apple's first silicon announcement that they have done that brings them into the step into ai, and there's a lot of things that are going to be following in the coming months, including their development conference in about a month from now, that will play into a bigger picture around this. so, the ipads are great, the discounting on the old ipads are excellent, the air announcements, again, tremendous upgrades from the previous versions. the ipad pros with the ma, leading with that, the brand—new chipset, as opposed to the mac, i think that's the biggest storyline, in my opinion. disney's streaming business has reported its first profit since its launch in 2019. the disney+ and hulu streaming unit saw an operating profit of $47 million in the first three months of the year. but shares in the entertainment giant fell after it said

the tv and park businesses face challenges in the months ahead. misleading advertisements are a hot topic in india and they are currently being deliberated in the country's supreme court. my colleague arunoday mukharji has all the details. expressing concern about the risks of misleading and deceptive ads, the supreme court has suggested a few precautionary steps, asking advertisers to fill up a self—declaration form and upload it to a relevant portal and share it with relevant authorities. the supreme court has also held accountable several government ministries, asking them to respond to court about what kind of action they have taken on any complaints they received about misleading and deceptive ads. before this hearing, the supreme court also cautioned fmcg companies against the advertisements that they put out where they claimed their products can cure certain illnesses. now, the issue of misleading and deceptive ads

has been dominating indian headlines for a while now, ever since the indian supreme court pulled up a very popular yoga group, baba ramdev, with millions of followers and a massive business empire, asking him to apologise for misleading ads. in fact, the yoga guru had to put out ads in the newspaper saying he was sorry for misleading advertisements, saying that his products could cure various ailments, especially during the covid pandemic. now, all these observations by the supreme court are being seen in entirety and as a caution and a warning to the entire advertising industry in the country. to finland, where one city is on an ambitious path to become carbon neutral. lahti was once a centre of industry and polluted. but it has gone through something of a transformation, as adrienne murray reports. warming up for another big game. it's notjust goals that the pelicans want to score. lahti's ice hockey team is trying to go green. this arena uses renewable energy and the team travel to domestic matches on a biodiesel fuelled bus. we are going to zero and we like to go below it, even to negative.

the biggest thing why we start this project, we like to show the way how to do things better. their efforts have helped win sponsors and also influence the fans. when we start accounting, almost everybody came by their own car. nowadays, they have changed their habits. lahti was once a polluted, industrial city. but over the years, it's transformed itself and is forging a greenerfuture. getting rid of coal was a major step. this plant supplies citywide electricity and heating, using woodchips and residual waste from forestry and households. if we look back to early 2000, our total emissions were overi million tonnes of co2 annually. by 2020, that was reduced to close to 100,000 tonnes, so a huge reduction — over a million tonnes — within 20 years. across the city, there's cleaner public transport,

like electric buses, bike sharing and lots of cycle paths. reuse and recycling rates are also high, and a big part of the work is engaging the local community. though takeup has been mixed, apps have also been tested out to encourage users to live more sustainably. everyone can choose suitable challenges for their life — for example, leaving a carfor a day at home — or then you can choose, for example, one month not buying new clothes. heating, transport and food are among the biggest areas to tackle. however, some habits are hard to change, like steering drivers away from petrol cars. there's still plenty more to do, of course, but a greener future is one goal that lots of people can get behind. adrienne murray, bbc news, lahti. before we go, shares of reddit have jumped by around 15% in extended trading, after it reported earnings as a public company
