Ads also have potential for disruption with Nostr; they don’t necessarily have to stay “evil” and shadowy. Users can be compensated directly for opting in to have their data aggregated and sold. Companies can have much more effective targeted advertisements with the ability to directly buy existing customer data whenever needed and by streaming sats to those who view and show interest in an ad. 

In my view, a P2P ad market over Nostr will become incredibly powerful for monetization in due time.
