I'm not sure what might be the solution for this but I'd be remiss to not mention that @Castopod's doing some great work in the Podcast realm.
Beyond the (obvious/unfortunate) advertising push places like Apple are doing to associate podcasts with platforms like theirs, there is – for the average person, I think – less cognitive overload to think of podcasts as something you get from somewhere.
Alt. sources, such as Castopod, may keep that easy association without curtailing freedom?
