And I would say Spotify is doing a social good. As a nobody artist, being able to point people to stuff on Spotify is really compelling. Any other way I'd have to force people into either buying or using an app they are unfamiliar with just to listen to it. That said I am not trying to make money from music, that is just foolish.
Well, I understand where you're coming from here, but that's not really Spotify doing a social good, it's just the inevitable effect of their cultural dominance. Everybody[1] has Spotify. But they've taken that position due to their unethical growth plan.
Anyway, I've realized that we're discussing multiple things, not one thing. Spotify can be bad for artists who want to make money off their art, while being good for those who don't want/need to make money from music.
[1] I don't have Spotify.
And in doing so, each has failed to realize better solutions for people. Uber & Lyft have increased our dependence on wasteful, dangerous, expensive personal vehicles. Spotify is a worse model than Bandcamp for indie artists. It's also a worse model than pretty much every other streaming service in that it pays so little to artists. So, yeah I don't like it when rich people break the law to get more rich at society's expense. We should be breaking the law to make society better.
