Agreed, and I would say what cloudflare does for the internet (their work on the IETF, generally letting small sites stay alive without needing an SRE to worry about DDoS attacks, etc) outweighs the general negative possibility of them being a potential single point of failure

Well the admin of a site could opt out of using cloudflare for the time being, a user could do literally nothing. Errors in Cloudflare can easily take down their servers and therefore the CDN and access to like 20% of websites. And Bugs in Cloudflare can even leak user data.

So cloudflare can grant DDOS Protection, CDNs and other exploiting protection, but can take down large parts of everything, temporarily or permanently.

Shhhh you can't just be reasonable here. This guy watched a YouTube video, he knows what he's talking about

If cloudflare decided not to host my server I would have a bit of downtime, a couple of hours, but I'd be up again on someone else's CDN tomorrow. I don't think OP understands the role of cloudflare at all.
