It was because at the time of the exodus from Reddit somehow the conservatives (echoed on the sub by that name) felt that protests were ridiculous and they were on Reddit's side. So less likely to be jumping to an alternative.
Somehow the right has turned into not meeting any authoritarian boot they don't suddenly feel an urge to lick?
In their defense, they don't see the authoritarian boot and feel compelled to lick. They see how their hated enemy, normal people, get upset because of that authoritarian boot and in response lick the shit out of it so those normal people feel sad.
