I don't claim that people are demanding advertising I am claiming the people demand free/cheap products that fit their exact demands to be immediately delivered to them The way that companies are solving "free or cheap" is by having someone else pay for the service on your behalf. There are only a few mechanisms for this that are "win-win" theoretically and advertising is the one that is the most popular. In order for advertising to be useful it needs to be targeted and attributable and it has to be fungible across advertisers. Therefore if you want to be able to create an ad-market to keep your product free/cheap then you need to offer the highest granularity predictions for your advertising dollar - hence why we have extremely granular ad systems.
