Somehow I think Podcasts will survive enshittification. The basis is just RSS and file hosting, so at its core, it's possible to create and distribute podcasts without huge capital investment. There's always gonna be some people trying to get their voices out and Podcasts still seems to be the easiest way to do that so until some better method comes out, podcasts will live on.
If you're talking about Podcast networks, streaming services, ad networks, then yeah, those might face some kind of enshittification and destruction, but no matter what, I'm pretty confident some good podcasts, and some good ways to listen to them, will stick around.
Truth. I was genuinely angry seeing how Spotify kept trying to buy up everything podcast related. Felt like I was screaming into the void about how platform exclusive podcasts are antithetical to the free and open nature of podcasts. I hope their billions of dollars invested into podcasts continue to bite them in the butts.
