why would a scientist need anti-social media?

[sgt]

Scientists have used Twitter for more than a decade before Elon took over. It was extremely popular and there were large communities of scientists there sharing all kinds of stuff. After it became X, they have largely disappered. Many just stopped doing that kind of social media.

Why would someone else communicate in a way that you disapprove of?

Well, because they are someone else.
