the ad sponsored podcast content CONTAINS the ads what are you proposing that more will add to it?
i don't even waste my time with podcasts in general because the ads are annoying and those are the ones my adblocker doesn't screen out, yes, the ones the podcaster puts into the content, i always skip ahead of those segments and the only pod i watch these days is SO and he only puts an ad at the end to subscribe to his actual service
i guarantee you that nostr clients with advertising will be the least popular, at least until there is wide adoption and then it will depend on how much they tamper with the feed to suck people in and keep them clicking, also, a dark pattern just like advertising as a revenue model
how else do you think it came to be that half the internet is run by companies that were spawned by spooks?
the advertisers sucking up market intel is just the stuff they tell you about
