Domestic governments shouldn't let hostile foreign governments the ability to exert soft power over 1/2 of their population. Hence why China banned all USA based tech companies from operating there.

As a Chinese grown up within the Great Firewall, now I began to really feel all the hypocrisy around the matter of "freedom of Internet". It seems the block of Facebook and Twitter in China is surely justified at the very begining, for the same "national security" grounds. China have exactly the same amount of reason to believe the US is stealing data or propelling propaganda by social network.

It seems there are indeed things that can override citizen's free choice even in the "lighthouse of democracy and freedom", and CCP didn't make a mistake for building the firewall. My need to use Shadowsocks to use Google instead of Baidu or some other crap was simply a collateral damage.

Of course, the Chinese censorship is way more intensive, but this act makes a dangerous precedent.

And this is why most countries should ban Facebook, Twitter and US social media.

The funny thing is that when China did that, it was unanimously condemned in the Western world as an authoritarian move, and often use as an example of why China was a dictatorship with no freedom of speech, etc. But now it's actually the normal thing to do?

The opinion is mostly not about control over recommendation algorithms; it goes out of its way to say that the data collection is dispositive. Check out Gorsuch's concurrence for some flavor of how much more complicated this would be with respect to the recommender.
