I counter with the fact that hosting something means nothing unless connections can be made. Well, unless hosting in itself is your end goal.
Even here on HN, there are plenty of comments about how someone can't connect to a website because it uses Cloudflare and Cloudflare decided to block them due to a dirty IP address, shady (read: hyper privacy focused) user agent, CAPTCHAs that don't work (see prior factor), or other factors.
Some form of DDOS protection is desired in this day and age, and Cloudflare provides a very convenient service to answer it. Unfortunately, this means the vast majority of the internet is routed through Cloudflare making it a singular point of failure/denial. Aka centralization.
