I think most of the nerds that might be able to strip inline ads would prefer to support (or at least appear to support) podcast producers and so wouldn’t have much interest in developing said app.
Also, stripping ads isn’t an easy problem given how unpredictable they can be. Some podcasts ads are read live by the same voices presenting the podcast without skipping a beat (particularly common with a popular DnD podcast).
The more practical solution is to use a player that lets you set distinct skip intervals for skipping forward and back. For example on my podcast app, when I skip forward it jumps 30 seconds ahead, but when I skip backwards it only jumps 10 seconds. That means I can jump ahead in roughly commercial length intervals until I no longer hear the ads, but if I’ve gone just a little too far then skipping back once or twice usually gets me close enough to the start of real content again. If you rely on an app to strip the ads, you’re practically guaranteed to remove some actual content, you’ve already put more effort into avoiding the ads than I have just hitting skip once or twice, and if you’ve removed content that you want to hear then you’ve got to go back to the original podcast and listen through the ads anyway. Why bother? Podcasts aren’t like YouTube where a third party is inserting the ads in random obnoxious places that interrupt the narrative or musical flow. Are they?
