I think most of the app devs so this for the love of the game and barely have time to work on there apps. These apps have been around for years are are great. I think the issue is no one knows where to start and its a very small part of PC 2.0 so doesn't get that much attention now so its up to us podcasters/listeners that got orange pilled to help the devs out.
there is a podcastindex mastodon that I can send you an invite to. Its were most people can be reached at. It bridges to Nostr but thats shit show tbh.
