For at least the last decade, Cloudflare has made the impression on me to be what Google wanted to be, in terms of "being good".
I can't remember when it was the last time I've heard something bad about Cloudflare. Then again, I don't use any of their services, even if I have an old account with them. I never saw the need to use them, but like what I see about the products they offer.
They seem to be doing much more good to the internet than causing trouble.
While there's plenty of other angles to complain about them, one of the more common ones is the fact that Cloudflare is just as happily providing service for the very same spam sites they claim to protect people against. There's plenty of blogposts that talk about this, but the one I'll give a link to is the one from Spamhaus[0], the guys who run the most popular DNSBL.
Spamhaus also mentions the main problem with their abuse form, which is that it forwards abuse emails to the hosting provider and the web administrator. They pretty much never do anything by themselves and neither the web administrator or the hosting provider have much incentive to disconnect spamming customers (since the admin is hosting it and the hoster usually stays outside of the risk anyway.)

Thanks for the response.
I figure that the discord at the root of the issue you're describing can lead to more uncommon complaints against them, bringing this to mind: https://blog.cloudflare.com/kiwifarms-blocked/
Are you serious? It seems that cloudflare is one of those companies that doesn't make itself heard much because it's better that people don't know how much pieces of sh*t they are.
