Perhaps, but on the other hand, if someone like Joe Rogan had a paid for subscription plan where you were paying him directly, instead of being forced into a membership with Spotify, would that in a sense be more open, in that you are able to vote directly with your cash who you are listening to?

Of course, if its an apple product, in a sense you are tied in to their system, but if it's successful, other paid for podcast variants could appear and then Joe Rogan can syndicate it to numerous vendors which have a pay-wall.
