Greg Sage is completely removed from every platform under artist's name

Everything under Greg Sage's name has been removed from Spotify, YouTube, apple music, any streaming. Does anyone know why? I know that it doesn't earn artists much money. I'm very guilty of utilizing these services, as I'm always on the move and physical media, however incredible it is, just tends to slow me down at times.

It is also difficult to find Greg Sage cassettes without spending a fortune on used ones.

Does anyone have any insight on this matter? Or why this happens in general. I would love to be more educated and have a better understanding of the subject.
