Hmm. My faith in the BBC's commitment to decentralisation and open standards has been damaged by the artificial month delay they added to their podcast feeds to try and drive traffic to their centralised Sounds app. I've been listening to the In Our Time podcast for 20 years and then they go and vandalise it as a growth hack. There is no way I am using multiple proprietary podcast apps so I end up listening to topica…
It's a shame because RSS podcasts are naturally distributed (probably because they date from back when that was the default mode of the web). No need to bow down to someone else's content rules - if you have a domain and the ability to host some fairly small files, you can have a podcast which can be loaded into thousands of apps across all platforms with no central authority
I'd also take that as a lesson to some younger people getting into decentralization afresh and thinking it requires heavyweight federation. You don't necessarily need a complicated protocol and your servers talking to each other. Just standard client interfaces and then the client can do the aggregation with distribution as a natural property, like the web
