This won’t affect most of the podcasts I listen to, as most of them seem to be funded by Patreon or similar platforms. I say “seem to” because I live in Finland, and there are very few auto ads on podcasts around here, but they are increasing.
Over about 5 years, I’ve skipped 8 days and 17 hours of ads, with the majority being for other podcasts. In that same 5-year span, I’ve listened to 418 days and 4 hours on one app, not to mention countless hours on other apps.
