:-) Cloudflare is amazing, yes. Everyone should use it by default, I say.
I hope for more diversity, for many reasons. One of which is that they are a know man-in-the-middle, that can see the plan text of what appears to be secure communication to the user. It operates in the US, it can be compelled to, and to do it silently, into using their position to spy on people.
That said we use them at work and I use them personally. I'm not doing anything "risky" at all. But there are many cases in history where suddenly the government changes and now you are. And apparently black people are always doing something "risky" in the US.
We'd have to basically quadruple our expenses without CF. Not to mention their available protections.
I vote for more diversity rather.
