It’s not that I care what people on that platform think. It’s that I care what shows up in search engines and whether my brand is diluted by people other than me.
So get an actually original brand name and sue people who fuck with you.
Headlines don’t get unprinted. If Muse quit Facebook or Instagram, especially after already having a presence there, it would be trivial for someone to swipe their brand identity and start posting horrible shit to generate headlines.
And it would be equally trivial for anyone to communicate to the world that they do not use facebook or insta, and that if anyone shows up there under the brand name they're a fake. It's not a parking lot. They're not in your space. If they impersonate you that's, again, something you could take them to court over. At no point are you required to support a pro-fascist platform by showing up to make sure nobody pretends to be you in a place nobody who cares about you should ever go. Holy shit, how is this hard to grasp.
