Sure, you can claim it was a dick move, and maybe it is (although why is a handle so valuable? "muse instagram" now links to the @museband and their followers were transferred). This is just some phony outrage.
It's also ironic that the overlap of people that find this offensive but were fine with social media censorship since "it's a private company" is > 0%
I would not want the potential fallout of the when the AI tool goes sideways. Or stupid requests. Etc
Let meta handle redirecting band questions to the proper account.
Curiously low signal.
The namespace belongs strictly to the service operator and they shuffle names around based on any arbitrary process and it's mostly vibes driven.
