I can’t speak for the “pre-migration” folks, but I was (I think) an early post-migration adopter (as soon as the spez AMA was over), and even I have seen a change. One thing is the desperation to fill the comms. with content, so Reddit repost bots are constantly flooding my All. Another, somewhat connected problem is the content posters (news articles, mostly) cross posting to all the related communities because not everyone is subscribed to c/news@whatever .instance, which is a flood in itself of the same post dispersed by other posts. It’s definitely more content (though not exactly doomscroll worthy, which is fine with me) but the content is repetitive because of these problems.
