Journalists are trying to find places to move over their audience since twitter put their audience behind a login screen
It's free and open to the world and they can just join any other server too if desirable.
I'm still looking for major outlets to set up their own servers and be able to follow name@newsorg.com accounts for their staff.
I've already seen one: https://social.heise.de/
Kidding aside, I do seriously question whether that move would ever happen without it being forced.
