Trump claims that it's a security risk, because its parent company is Chinese owned, but the reality is that he's chuffed about how Sarah Cooper has gone viral doing satirical lip syncing of him.
In any case, this court case will almost certainly result in an injunction that will last well beyond election day:
Made-in-China social network TikTok has decided to challenge the Trump administration's looming ban on its service by taking the matter to the USA's courts.
On its qq account and in a statement, TikTok owner Byte Dance offered a two-pronged rationale for its actions.
The first disagrees with the Trump administration's suggestion that TikTok shares data with China's government and is therefore a threat to national security. ByteDance, the company that owns TikTok, said it has tried to explain itself to the administration and find a solution that would satisfy US authorities its service is safe.
The second strand is an alleged "lack of due process" during those talks. TikTok spokesperson Josh Gartner said the Trump administration "paid no attention to facts and tried to insert itself into negotiations between private businesses".
TikTok allows people to share short videos.
The ban on TikTok was enacted with an Executive Order that relies on powers designed to let a US president act during a national emergency. The power has not previously been applied to an entity like TikTok so the case may well rest on some gnarly legal issues rather than the nature of TikTok's activities.
The idea that it could be a threat to anything than it's users' or Donald Trump's dignity is simply ludicrous.
