The issue it had is the same, but the opposite direction. Lefties used to get recommendations / for you of other lefties. And that’s what they liked, as they were close minded to other views.
Now they get a selection it’s a “right wing” platform.
So the left used to dislike it as it was clear where Twitter allegiances lied. Now with Musk owning it, the view is that it’s a right wing platform as that’s where his allegiances lie.
The truth is that real truth seekers shoukd read a variety of opinions, which I believe is what Musk is trying to do. However, his posts are so anti woke, it’s easy to disagree with that …
Personally I think most who leave will come back, as they realize they were addicted to getting upset at things on Twitter.
