The proposition, is to block all Cloudflare hosted websites. While the proposition is here for privacy, and anti-monopolisation of Cloudflare attitude by boycott, It doesn’t have anything to do with the Tor network itself.

Completly blocking services just because they treat badly the user privacy, or browsing attitude (Using the Tor Browser, Adblockers etc…) isn’t the main goal of the Tor network, Tor browser, Tails or any of their projects that´s related to this issue.

Also, actually blocking stuff seems to make you more unique, hence the non-presence of LibreJS or adblockers type of extensions or protection built-in, despite being beneficial for the most Tor Browser users.

Same goes for some malware/trackers blocklist built-in the Tor relays.
