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.
I use podcast addicts' auto slip feature. Most podcasts I listen to have a set ad of a set length at the start or end. You can set an auto slip on a per subscription basis. Works for me
