If they leave Twitter, where are they going to go? Artists need to promote themselves. They sure aren't coming here to promote themselves. Twitter has always been where people go to keep up with their favorite artists whether it be art, music, comedy, etc. If they leave then they're shooting themselves in the foot. Twitter is still massively popular even if you don't agree. Same goes for Reddit.

People who have made a living promoting themselves on Twitter aren't going to leave it just because Musk is a dumbass. Most artists as you mention typical have business emails in their profiles. Until Musk does something to fuck with their income, they're staying.

It's the same shit when people on Reddit say they're abandoning COD this year because the devs pissed them off only for the game to have the highest sales ever. You, me, Lemmy users, and Reddit haters are just a fraction of the people who use those sites.
