I can't speak for everyone, but they increase the security and performance of websites for free. I'm sure a lot of people would like to move away from Cloudflare, but every time I try to find an alternative, none of their competitors even come close. Let's say I moved one of my websites to Bunny CDN and transferred 1TB per month, that could increase my website cost by $120 per year.

The sad reality is that Cloudflare can basically do whatever they want until another competitor offers a good free alternative, which is unlikely because Cloudflare has a monopoly. We would effectively be asking millions of websites to pay to use a service with less features.

I'm still looking for a good alternative, so if anyone has one then please let me know.
