Not really the problem, some mods just bury threads about it, you can see an arrogant mod from self-host subreddit in a thread, attempt to plead to move elsewhere: https://www.reddit.com/r/selfhosted/comments/1gmv76n/is_reddit_going_to_remain_the_primary_space_for/ (this was a week ago) You can see why some still didn’t by the replies, and lack of understanding how to use Lemmy isn’t one of them.

Bridgy.fed is nice for bridging also for using both at the sametime. I think what a lot of people like on BlueSky is the feed algorithm without having to curate yourself like on Mastodon or posts sorted by the time it was posted. That probably makes a huge difference.
