Ad-blockers on the internet are justified because of invasive tracking. Radio and podcasts have no such thing, and ads are are central to their sustainability.
If you want to push the world to improve, you can't just rage blindly, you have to identify and move towards a solution that's sustainable for everyone. In the case of ad-supported businesses and services, this means non-tracking, non-intrusive advertisement (combined with subscription models, but that doesn't work for everything).
If you want to push back against tracking in ads, you have to support non-tracking ads. Otherwise there's no incentive for anything to change.
