I would assume that since this whole thing is more or less a result of left-ish policy, and the opponent in the scenario is the far-right platform formerly known as Twitter, lead by the aspiring far-right icon Musk, the right-wingers would more likely opt to complain, cry several rivers and eventually turn to alternatives catered specifically for them (not even sure which ones are still alive after former tweetyplace took the crown) instead.
Haven’t done a vibe check on bluesky, but I assume it almost has to be more tolerant and potentially more progressive-ish than the old nazibirdhouse. If you lean towards the far right, why choose that, if alternatives exist?
