I also don't know if the crowdsourced skiplist works for podcasts as well as for youtube ads, since I think a larger proportion of podcasts use dynamic ad insertion - do they have consistent length? Might mess up ad tags/flags
Ultimately, IMO there's too many niche podcasts out there for sponsorblock route. Better to have AI solution to figure out and tag ads + sponsors + filler content to autoskip according to timestamp on downloaded audio file podcasts which could be variable length due to localized ads.
Seems like a lot of podcasters haven't migrated from google music / google podcast to youtube music podcast. The ones that do does have youtube interface but I rarely see any get tagged by sponsorblock. Honestly one of the things I was looking forward with the google podcast -> youtube music podcast clusterfuck.
