I don't really understand why anyone who claims to be a proponent of a free market economy has an issue with a private corporation deciding what type of content they want to broadcast. JR sold his catalog of intellectual property (podcast episodes) of his own free will and was paid very well for it: about $100M from what I can gather. What Spotify chooses to do with it is completely up to them, even if they bought it…
This is a larger cultural question and will determine where we go from here.
Are we still a society that values free expression and open debate?
