Cloudflare is also a threat to internet freedom. Use anything other than official sanctioned ("supported") browsers and software/hardware and you'll be considered not a human according to them.
Even if you use an up to date, supported browser, any setting you change which makes it harder for them to fingerprint you, also automatically considers you a bot, and many have complained of getting endless captcha loops they can't overcome.
Been getting stuck in constant captcha loops lately on waterfox and it's unclear what i did, if anything at all, to cause it, since the loops tend to go away for a week or two before returning for a few days and repeat.
I'm pretty sure i didn't do anything, and they just randomly decide to brake check people with adblockers and the like even if you disable them after.
