Maybe it's anti-Elon, or maybe it's anti-the-things-Elon-is-doing-to-Twitter. Just because the people who like Elon have joined a cult of personality doesn't mean the people who dislike what he's done to Twitter have done the same.
For example, I still think Tesla's are cool cars and Space X is doing exciting things.
For me, Twitter has become absolutely unusable. Every person on my FYP and in the replies is someone with 328 followers, crappy opinions and $8/month to burn. I went from loving Twitter for over a decade to finding it utterly devoid of anything interesting anymore. If you happen to like it more now, that's great, keep using it! But a lot of people simply don't get value out of the app anymore.
