I would defend the right to criticize. My point is that artists and consumers have a choice.
Maybe there's a significant percentage of Spotify customers that give two shits about the art and just want to play some background music. That's ok. There's also artists that can thank Spotify for new fans and new listeners that can thank Spotify for new artists to listen to.
This moral outrage over Spotify tends to overlook that there are tradeoffs and every market has these problems. Blaming Spotify for killing a genre is crazy dumb to me. I'm not going to stop listening to lo-fi hip-hop cause Spotify has ghost artists and AI music on it. These bedroom artists have done what would have been impossible 40 years ago and the fans they've gained aren't going to go away. That's a testament to streaming platforms.
