Not to hammer the point to hard, but de-concentrating power is the exact reason why it is better to have moderation decisions across multiple layers of the network stack rather than in level 0 (the government).
Forum messes up on moderation? Not a big deal.
Web host starts making bad decisions? Tons of options.
Clouldflare banning you? Tougher, but there are multiple CDN services, if Cloudflare becomes evil it's not necessarily the end of the world.
ISP banning you? Now we start getting pretty dangerous, there are fewer options available to services and if moderation decisions are made poorly, that can have effects across the entire network for everyone.
The government prosecuting you? This is level 0 of the network stack.
The way that we guard against concentration of power is by de-concentrating it. Cloudflare (and to be fair, other large Internet companies too) are arguing for the opposite of that. In the specific case of Kiwi Farms, maybe this example is so egregious that it does make sense to have some new laws. I kind of agree with that. But no good law will be enough on its own to get rid of Cloudflare's responsibility, the only law responsive enough and fast enough to do that would be one that violated free speech rights.
