That may be the case, but anyone can use ATProto. Unlike X where reach is suppressed for ideological motivations, or Mastodon with the federation turf wars, anyone can use it, regardless of their politics. If you disagree with the ideology of the majority users and avoid it for that reason, it just perpetuates the problem.

Unfortunately, I suspect it is only that way at present because the "other side" is perfectly content to continue existing in a communications environment that prioritizes them, rather than one that is actually open.
