It's not all that hard to curate a feed without that stuff. Block people who annoy you, mute words/phrases that annoy you, and follow people you enjoy.

Curious as to why people think this (other than partisan trend-following). I've been on Twitter since 2009, and it's arguably in the best spot it's ever been, apart from Grok being pushed so aggressively. A lot of people still build publicly on Twitter. If you're conservative you can follow conservatives, if you're liberal you can follow liberals. I find Elon annoying, so I just muted his account because it seems like it was being algorithmically pushed, especially during the DOGE days. But I do follow politics pretty closely, and it seems relatively balanced overall.

Not sure if it turned into Musk's idealistic "town square," but it's certainly more interesting than it was before.
