You have the freedom of speech to manipulate and be anti-democratic as long as you are the US government or bound by its control.
But it's not though? They are requiring divestiture from an adversary nation, not because TikTok is somehow inherently “manipulative and anti-democratic”
Nothing about TikTok has to change except who owns the company (unless of course the owners are manipulating the company's operation, in which case divestiture would indeed by quite disruptive).
What’s perplexing to me is leftists love how companies in America can be forced to sell and broken if they are declared monopolies. But if an app is declared an agent of foreign powers suddenly forcing a sale is wrong? It makes me feel even more certain that HN is astroturfed by Chinese bots because who cares
I despise communism myself, as my country went through 45 years of it. I agree with TikTok being forced to sell, and I'd like to see all social media sites offer more transparency mechanisms to NGOs and government agencies to show how their algorithms really work to have some watchdog be able to check if what we're seeing is heavily manipulated, especially during election years.
I suspect that people pattern-match this declaration to McCarthyism.
Additionally, the US has been invoking national security for a series of extremely dubious moves recently as well -- e.g. Biden's latest decision to block the sale of US Steel to Nippon on shaky grounds of national security, and his administration's recent policy to introduce export limits on GPUs to all countries except 18 (most US allies, NATO or otherwise, are now unjustly being restricted in how many GPUs they can import). Coupled with the incoming Trump administration's threats of trade war and expansionist designs on Greenland, people -- especially non-Americans, also in countries that have historically been friends of the US -- are very quickly running out of goodwill for the US, and in light of these events naturally the TikTok ban is seen as just another draconian attempt by the US to practise (economic) imperialism.
