The failure of Mastodon to thrive even when Twitter itself became very vulnerable unfortunately tells me that people actually want this pathologically bad behaviour. Lots of friends who slagged Twitter and Facebook etc for its anti-social aspects turned around and tried Mastodon for a few days and then came back to me with a "there's nothing happening there" and it's "boring" etc because they were fundamentally expecting to be force fed entertainment just like Twitter. Lots of comments on hackernews to that effect, too.
That's fine. I never liked Twitter anyways, but I do think it's interesting how two faced we can be about this.
The engagement hackers found a market and met it. Not good, but true.
