Why don't I use Bluesky? Because it's loaded with the same kind of low-effort, self-promotional stuff that caused me to leave Twitter. For instance, this. Now, maybe there's something there, but it's just an old man shouting at the clouds in this form.
For a post like that to have value, the author would need to give an example or provide some kind of supporting evidence. The only goal behind posting something like that is to use toxicity as a tool for interaction. We used to call them trolls, but these days trolls have high follower counts on social media, so they're simply playing the game.
