Could you elaborate a bit further? I don’t see why this is necessarily true.
At the end of the day, the podcast is served by one of these hosts, regardless of how it was discovered. It can be observed that they’re centralized when media companies make exclusive deals as Spotify attempted with JRE.
I wouldn’t disagree that podcasters are in control of distribution; that’s not actually exclusive with the distribution being centralized. The point I was making about the exclusivity deals is just that these platforms have started to try -- and likely will continue to try -- to entice some of the more popular productions into such deals, which would necessarily increase centralization if they go through.
It’s a cynical perspective so maybe best kept to myself but I see all the right pieces for a UX bait-and-switch. I suspect the parent commenter (to whom you asked the initial question) sees the same thing. I think it’s seemingly intentionally misleading to call this decentralized; like “that’s what they want you to think” as a paranoid way of putting it. Regardless of any motives, it seems to serve certain interests that this is seen as decentralized, and I don’t think they’re the interests of podcast fans. Food for thought, I guess.
