Apparently Cloudfare provides services to pornography websites. Click
Cloudflare has a LOT of customers. That's like saying I shouldn't get gas at that service station because a pervert also gets gas there.
And Cloudflare isn't doing the hosting. It's just a buffer, a go-between. It puts up a shield, with servers like CC on one side and users like us on the other, and passes data between servers and users through the buffer. When CloudFlare notices someone is trying an attack, it cuts that connection.
So that's more like saying I reject the army protecting the place where I live, because a pervert also lives in this country so the army is protecting the pervert too.
Or there's something fishy about that christian bookstore because it's in a mall, and there's a Victoria's Secret in the same mall.
