Moderators get the worst backlash everywhere in the world. The only difference is that Cloudflare continues to refuse the fact that they have quite a lot of power over whose traffic they let through. When you, basically, govern 20% of internet traffic you must take the responsibility for it as well.
This article is a nonsensical shout in the air. Cloudflare, like Google, is not looking over every single request that goes through them. They take these actions after enough noise is raised to highlight the issue. The problem is that Cloudflare will become prone to bullying.
What I mean is that if I have a good number of fanatic followers, I can raise noise against a rival platform and get Cloudflare to, at least, scrutinize it and, at worst, deplatform it. Cloudflare will need to set in place some policies to protect themselves from this.
If Cloudflare does this kind of thing enough times, they will unintentionally become a policing force. That's really not a good place to be in for a business.
