It’s how the anti-fingerprint features in browsers like LibreWolf and Mullvad are supposed to work: make all copies of the browser appear the same, which means forcing some options in the browser settings, so that nobody sticks out. Brave chooses to do so by randomizing some of your browser fingerprint data, which really doesn’t prevent you from standing out, it just means that your fingerprint info the trackers collect isn’t going to be accurate.
Pretty much how Bluesky took off at all. It’s just the polarization of the platform style reflecting the polarization of society: Twitter/X went right-wing so the (center-)left made their own platform. It’s the same thing the right did when Twitter was politically censoring right-wing content before Musk bought it and Trump made Truth Social, the only difference being that Bluesky got the Big Tech and mainstream media blessing. Musk said he would stop that sort of censorship but just reversed it to censor left-wing content. Nobody actually wants a truly free platform, they just want their echo chamber.
