It'd be "stolen" only if Muse (the band) didn't agree to this, or were strong-armed into this.

Nothing in the article about a lack of consent, only assuming. Random source. Conjecture. Random quotes from everyone except the affected parties.

Curiously low signal.

that's how it has always worked.

The namespace belongs strictly to the service operator and they shuffle names around based on any arbitrary process and it's mostly vibes driven.

If I were the band, I’d do the same.

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.
