Because then you don't have to change RSS feeds, web hosts, move your mp3 and videos over to rumble, get cancelled there, etc.... Your source of income from a podcast is the real issue and getting cancelled means that you lose subscribers when you move to the new platform. I suspect he makes more than 75000$ a year on the podcast.

A decentralized podcast/website/file hosting fixes this.
