I think the whole "buy MP3 from bandcamp!" thing is such a yawn. Sure, I get the whole "ownership" angle or whatever. I'm not about to run two apps to listen to music on my phone. I already have a Plex server. I could just load the MP3 onto that. But I won't.
I want variety. I want Spotify to constantly be throwing new artists at me. I love this. Spotify singularly helps me discover so many fantastic new artists, who go on to become my favorites, I go see them live, I buy their merch, Spotify does this to such a better degree than anyone else in the industry that its become literally impossible to quantify how much a "fair" amount Spotify should pay artists actually is. I never would have discovered `INSERT_BAND_NAME` on Apple Music. So sure, alternatives might give bigger pieces of the pie; but Spotify is the only player actually making a bigger pie.
I think the author would just prefer Apple Music. If you're boring and predominately only listen to the same few dozen artists, then absolutely you should be using Tidal or Apple Music, or buying MP3s, as these services will pay artists better.
