It isn't Cloudflare's aim to exclude Tor users from the web. On the contrary, they have gradually made it easier over the years. Tor was really unusable back in 2015 where every other site required an unsolvable reCaptcha.

Since recently, Cloudflare's bot detection works slightly differently. They show fewer captchas now, but one consequence is that Tor users are barred from access more often. I'd imagine they're working on it and we just have to be patient. In the meantime /u/magnora7 could change the security level in Cloudflare, but I could imagine him wanting to keep it this way because we have enough spam to deal with already. Maybe require new users to solve simple captchas for the first 20 posts, and then lower the Cloudflare security level?

You could also use Librewolf, which combats fingerprinting similarly to Tor Browser. Then you just need to hide your IP address. You could install a VPN, plus a VPN browser addon inside Librewolf from a different VPN provider. This way, the NSA needs to control both VPNs to find out who you are, and also care enough to go through such lengths to track users. (They may or may not, my guess is that this suffices for avoiding mass data collection.) But for this to work you have to go to preferences -> privacy & security -> uncheck "Query OCSP responder servers". N.B. you're exposing yourself to possible MITM attacks this way, that's the trade-off. If you don't want to do that, another option is to go to network settings and manually configure it to use a Socks 5 proxy that you found on the web. Do let me know if you find a good free one, because I don't know of any myself, they all suck.
