bitmitigate lost their upstream of voxility for hosting 8chan (voxility german company lol)
vanwanet lost their upstream of ddos-guard because of legal request from ROSKOMNADZOR
vanwanet, like bitmitigate, made new agreements with different providers. both still exist and vanwanet even hosts 8kun to this day.
8chan was kicked off by cloudflare not because of the decisions of others, but by their own. So this does not rebut the original point of cloudflare being the "best", and is a bad argument in itself because other providers no longer have to follow russian law.
When you send make any request to view a page, make a post, login with your username/password, or any other communication to a site using cloudflare, cloudflare can see all of that information. This is the definition of a "man in the middle attack" because you expect the encryption to be between yourself and 8chan.moe, which is not the case. This is an incontrovertible fact. Whether you consider others schizophrenic for recognising the problem with that is irrelevant.
