And has that stopped them from censoring KF to an extreme extent? No, the site would've been gone if Null wasn't so persistent. 8chan is pretty much dead, as are many other attempts at "free speech within US law" websites and forums.
They just circumvent governmental authority through sheer corporate power. The government cannot censor you, but a website needs support, a host, DDoS mitigation, CDN, a domain, etc etc.
If no one does business with you, your site is essentially censored and gone, without the government ever lifting a finger. Let's not be stupid, they don't care about any amendment, they'll go after the support structure instead.
Fact is, if trannies on twitter start a crusade against your site, they'll go after every possible venue and company that your site needs, just to have the site removed. They have no lives, so unlimited time and money, and they spend all of that on DDoSing and spamming tech CEOs.
Had VanwaTech not been here, kf would've been relegated to the dark web. But they'll probably go after VT next.
