> So I went back to X, which for all its flaws at least has interesting content and, perhaps most importantly, has no equivalent to Bluesky's "nuclear block", so you can follow, and even participate in, divisive discussions where someone has been blocked.

In other words you agree with Musk's reasons for buying Twitter and opening the place up to other voices than just those which fled to places like BS. Good for you to acknowledge this and to realise that just being in the same place - virtual or physical - with others who you happen to disagree with does not 'taint' the place nor does it make it impossible to interact with most of them except for the looney fringes. BS was bound to end up like it did just like e.g. Gab ended up the way it did: it attracted those fringes, the I-support-the-current-thing types, the follow-the-leader factions, the I-am-very-special-and-you-should-venerate-me crowds. Some of them remained on or returned to what is now X where they do their thing but there's not enough of them to set the tone so you can ignore them.
