It doesn't negate the validity of wanting compensation for Spotify plays. Not being on a music service is one way to let your listeners know that the system is fucked and maybe make it change.
If you think on principles, Spotify should in the long term aim for maximum customer satisfaction. This means optimizing the satisfaction per customer instead of per music play, seems to be currently done. By concentrating money on bands each user listens to each of those bands (getting more money) should theoretically improve in quality (and give Spotify more attention), increasing overall user satisfaction. It's a simple reasoning.
