Musk's idea is to piss off 10% of the left and right of the spectrum and keep the middle 80% happy.
The left 10% will hang out on Mastodon or Fediverse, the right 10% will go on Gab or whatever. I think what's happenning is great for all. You do you™.
Gab is a Mastodon fork that's basically locked out of the Mastodon Fediverse by the moderators. There's no reason why Mastodon qua infrastructure should be identified with the "right".
