Yes, but companies need ad revenue to make sufficient profit these days. Just shows how overvalued all corps are today. Nostr clients and apps will make the same mistakes somewhere down the road. And those that rely on such means for revenue will ultimately prove to be the least innovative of all and die out. We're literally witnessing that right now with the current state of the internet. Advertisements have always been a way to fuel engagement without providing the necessary or desired information while simultaneously churning in corporate profit. Modern-day corporate marketing has essentially just become a way to suppress human intellectual curiosity through the use of data collection and algorithmic indoctrination.
