I guess this comes down to the idea that a podcast doesn’t exist unless it’s in index or directory x. That’s silly. No one cares about podcast directories.
I suppose it is the case that if a show isn’t on iTunes it’s going to be hard to find an audience but iTunes isn’t a gatekeeper. Anyone can list their show on iTunes - it’s the first thing you do when you create a podcast. EDIT: Oh I see. The problem is Alex Jones. Well that’s true, in some cases, Apple is a gatekeeper. It’s much less so than YouTube, but you don’t need either to exist. You’ll just have to find other ways to market yourself. One good way would be to raise a ruckus about how Apple, Google, and Twitter are “violating your free speech rights.” (hint: they’re not)
If a podcast has an RSS feed (which, in my opinion, is what makes it a podcast) then any podcast client can add it directly.
A podcast should probably have an associated web site, for a variety of reasons. If it does, a Google search will be sufficient. Not being on Google might be a real problem, but you’re really going to have to work hard to get yourself delisted from google. Weird beliefs won’t do it. Trying to game Google search, on the other hand, might.
Any assertion that a show has to have an entry on podcastindex.org or a similar directory is complete nonsense. Ask yourself, if you wanted to find a show about something you are interested in, where would you look? (https://lmgtfy.com/?q=alex+jones+podcast)
Now there’s a separate issue of marketing. If you want to grow a show you need people to know about it. The #1 thing you can do is convince iTunes to feature you. A close second would be to be featured on Spotify or iHeart. These things are hard, very hard, but there are other things you could do, like buy ads on Facebook or Google, that would also help.
Marketing a show in this era of content oversupply is a big challenge, but getting your show on a podcast index no one knows about is probably going to do much.
It’s my guess that what they’re really saying is “if you’re a nutjob conspiracy theory podcast we’ve got an index for you.”
ANOTHER EDIT: Oh I just listened to the audio. It’s Adam “f’ing” Curry. Adam did this once before with Mevio (née PodShow). Remember Mevio? No one does. Adam, of all people, should know that RSS is all you need. Joe Rogan leaving RSS behind means he is not a podcaster any more. Without RSS Spotify is just an internet radio network. It is indeed the opposite of free speech. But that’s why I am such a strong believer in RSS. RSS is totally independent of any index or directory.
