Are there any negative externalities from this? If ad fraud is a self-contained cat-and-mouse game between Google and bots, I'm fine with watching from the sidelines.
If we want to wean off of this surveillance economy, both consumers (via ad block) and companies (via organic demand) need to leave the platform. Otherwise we will end up with scams to fill either side of the market. Consumers with Adblock get replaced with bots, companies get replaced by Taboola-style clickbait.
