I think there's a massive gulf between an employer's behavior and an employer's transparency; lack of transparency is not in itself a reason to condemn a person for working at a place. There's no actual evidence that Muse Group is actually installing this telemetry in bad faith, nor any actual evidence that they wouldn't be willing to modify the details so it's acceptable. They seem to be absolutely horrible communicators, but ones with a product that does good in the world (and yes, I think that their efforts to thread the needle between the litigious whims of the music industry and the effort to democratize access to sheet music and the tooling around it are societally necessary). So I think it's appropriate to be critical of how they handled the situation but still support the idea that the people working there can be doing so in good faith.
