I’m happy to adopt a new podcast app if it has sponsorblock natively or through a plug-in. Otherwise let me know if there’s some other way to make it work. I don’t see why it wouldn’t work as all of the segments tagged for skipping are crowdsourced which would also work for Podcasts.
On top of dynamic ads, another problem would be decentralisation of podcasts. Many of them are released on several platforms simultaneously, and some sort of extra work would be needed for this to work accordingly independent of where you’re listening to a particular podcast.
