I've been hosting web sites on my own bare metal in colo for more than 25 years. In all that time I've dealt with one DDoS that was big enough to bring everything down, and that was because of a specific person being pissed at another specific person. The attacker did jail time for DDoS activities.
Every other attempt at DDoS has been ineffective, has been form abuse and credential stuffing, has been generally amateurish enough to not take anything down.
I host (web, email, shells) lots of people including kids (young adults) who're learning about the Internet, about security, et cetera, who do dumb things like talk shit on irc. You'd think I'd've had more DDoS attacks than that rather famous one.
So when people assert with confidence that the Internet would fall over if companies like Cloudflare weren't there to "protect" them, I have to wonder how Cloudflare marketed so well that these people believe this BS with no experience. Sure, it could be something else, like someone running Wordpress with a default admin URL left open who makes a huge deal about how they're getting "hacked", but that wouldn't explain all the Cloudflare apologists.
Cloudflare wants to be a monopoly. They've shown they have no care in the world for marginalized people, whether they're people who don't live in a western country or people who simply prefer to not run mainstream OSes and browsers. They protect scammers because they make money from scammers. So why would people want to use them? That's a very good question.
