Imagine in the current world that every other countries take the same approach and kick out that now hostile influence (basically banning Meta/Apple/Microsoft/Amazon). How would these companies look when limited to domestic market ? And is that really the world we want to live in ?

China and Russia already does this. Very few other nations have reason to, but if they want to pick between American, Chinese, or domestic websites they are free to do so and I'm confident the vast majority will pick American.

The comment chain you’re replying to is advocating for reigning in “our own” companies, regardless

Kicking out the hostile state solves the immediate threat from China. But what about threats from our own (current and/or future) government?

We can handle our own companies with regulations that reflect the fact they aren't owned by a hostile state. We need to be much much more restrictive with china and also restrict our companies ability to work with them when it comes to data and technology sales

I find it fascinating how China is described as an hostile state when it's manufacturing the vast majority of our goods.

Are these two things inherently contradictory? They're currently flying missiles and threatening one of our allies. Can you interpret that as not a hostile enemy?

That is only a problem if value profits of a few companies, that don't even pay that much of taxes, over your citizens. Unless, of course, FB and Co. are doing for the letter agencies what TikTok is doing for the Chinese. In which cade it never really was about the companies in the first place.
