Can’t imagine this policy lasts more than a year or two given the rate that AI tools for music are improving. Once the tech can reliably create high quality dry stems of instruments, backing tracks etc. and automate professional-sounding production work (which most musicians do not currently have access to) everyone is going to be using it even if they won’t admit it publicly.
Some people are cursed with being able to recognize reuse or samey backing tracks...
Just a couple more months and a couple more trillion dollars to Altman!
