Patreon allows creators to for a fee serve additional media content via it's app which is agnostic of media type. (IE music, coding, youtube etc.)

Most people pay for things for convenience and perceived value. There is very little convience or perceived value in having to go to a mobile/safari/ios website, log in, and then download a for example 1gig podcast tothen have to find it in my "downloads" and then play via some media player.
