yeah but it amounts to straight up censorship. Someone in the government decides what is safe for the citizens to see. How do you even ban it, does the US have mechanisms in place to enforce a government ban on a web site/app?
Yes the US has a mechanism to ban a company and that should apply to that company’s app. It’s just trade restrictions like with Huawei. Banning a website will be harder, but by banning advertisers from paying for ads it’ll destroy the profitability of serving American consumers.
