Unfortunately, I feel that switching to Bluesky is not the correct move if we want to defend against "musk-ism". They've already banned a tonne of people for political reasons. The larger they get, the bigger a snack they become for "investors" and businesses. It'll just turn into "Twitter with different logo" and eventually fall into the same exact pitfalls as Twitter did.
With all its problems and shortcomings, Mastodon seems to be the only sensible option.
