I guess not every single ad is about Brainwashing. If that's the case of your wish, then every single company on the planet would go bust because every company would be selling something to you through ads or pitches at some point.

I hate Display ads because they're content heavy, irrelevant and suck my personal information. But podcast ads are not targetting nor using my cookie or phone id. It's just some content creator is getting paid to get the word out and in fact the podcaster would make it clear that this is an AD unlike in many other platforms where inline and native ads are common.
