Yeah, I didn't mean to suggest that I think Cloudflare was wrong. And given that they did the thing while worrying about the consequences, they clearly figured it was the right thing to do also.
As far as the basic elements of life - utilities and travel access - it's good that they're effectively guaranteed neutrality by governments. Given that living without running water and power is illegal in much of the US, it's obviously not reasonable for the providers to cut people off at will.
Hosting is certainly not any kind of right. Cloudflare's position is a bit different, because without DDoS protection an unpopular site will be permanently inaccessible - it's not just "go do it yourself" but "people who dislike you will effectively shut this down". Even there, though, you could plausibly find another provider or make an attempt to do it yourself. Internet access via ISPs is far more fundamental, which is why I don't mind Cloudflare's action but have serious objections to UK-style mandates that ISPs block certain content.
I suppose my larger question is where the bounds lie on speech as a practical right. It's easy to say "we're not stopping your speech, just your ability to put up your own website". And in reality, hateful content similar to what Cloudflare targeted shows up on all sorts of other blogs, forums, etc. But "you can't have a site" is tantamount to "you can only say this if you find another private party willing to leave it on their site". When we look at physical equivalents, saying "you can publish these thoughts if a mainstream paper will take them, but you're not allowed to print zines" would obviously be illegal, so I'd object to government-ordered shutdowns. But "somebody took all your free zines out of the box and burned them" is probably fair game between private entities, and is a closer analogue to "no DDoS protection".
Even more broadly than that, I think we have a pressing unsolved issue of private actions which are implicitly government-ordered. (This doesn't apply to the Cloudflare thing.) This was a big issue in the 1930/40s, with press and radio content being "managed" via the threat of IRS and antitrust investigations, but it was never actually resolved - practical changes just obviated the issue. Between TV consolidation, "safe harbor" laws, online payment processors, and large tech companies with strong government ties, that concern seems to be rising again.
