My main beef with spotify is their attempt to privatize and monopolize podcasting.
Spotify offers audio hosting and a large userbase, but does not provide rss. A few people I like are trapped in this, and I have no way to listen to their shows apart from using spotify. They refuse to understand that this is an issue, just like youtubers are ok with lock-in.
Podcasting infrastructure is not monopolized yet, like video is. It is even bigger problem for me than underpayid artists.
So boycotting, and if you undersrand that, you should too.
I choose to blame platforms for vile intents rather than users for ignorance. I don’t see awareness of politics of technology as obligatory for all authors (even less for users), but creators of those platforms know damn well what they are doing.
