That's just plain bs...
Eg
1) they have customers and their customers want protection, with minimal downsides.
2) Cloudflare is the only one with support for Tor. I'm 100% sure you didn't knew that.
What "examples" do you have to blame them for something they aren't doing? Based on what?
I'm getting tired of people blaming Cloudflare for providing a service that no one else can provide for free to small website owners => DDOS protection.
