Ok I just read it as well and apparently the problem isn’t so much that he made private copies, but rather that he live-streamed the album after having sold it, and now the new owner wants him to destroy those copies to ensure it won’t happen again.
If I read the article correctly, the problem isn’t so much that he made copies, but rather that he live-streamed them to the public after selling the album.
If he had just kept them private, no one would have ever known, but now the new owner wants him to delete those copies to ensure he doesn’t do it again.
