Darius Kazemi, the issue with cloudflare for me personally is that they harass me with captchas, or outright geoblock me, either just because I'm Russian, or because my IP address (something I don't have much control over) isn't "good enough".

The second issue is more of a political one — I don't like the idea of a single company seeing this much unencrypted traffic on the entire internet, and then using some arcane algorithms on it to determine whether someone deserves to be a visitor of a particular website.
