That's not the true reason. The reason is that some clever people have found out how to earn money with fake musicians. As a musician myself I can tell you, that such operations make the already completely unjust compensation scheme even worse for real musicians. But even if this scam was avoided, we still would suffer from the exploitative and abhorrent compensation scheme imposed by the record monopolists (who simultaneously claim to represent the interests of artists while primarily lining their own pockets).

If you are interested instead whether it was a real artist or just an AI (or a "stunt performer" pretending to be an artist, which includes all people who can't sing in tune without autotune), then you should be as consistent as the food industry. Personally, I'm more interested in the music itself. It's nice to know who played it, but that doesn't change the musical quality.
