"For users who opt in, Brave can deliver better quality ads, without the risk of personal data leakage. We do this by using local machine-learning to understand the user better, and making local decisions as to which ads should or should not be shown, and when (the user controls all of this). Furthermore, the user gets 70% of the ad revenue for browser-private ads."

Sorry. This is just wrong. You don't nor never will have the volume of data that the major ad platforms have collected for 15+ years. You don't have the pure analytical power of these companies in compute capacity. You will not serve better ads by disabling third party retargeting platforms.

There are many positive ways to spin an obvious blockchain-craze inspired endeavor, and I applaud the Brave team for blazing a trail, but you are calling out all the wrong value propositions.

Fraud is not as big of a deal as you state it is. It is not a problem for the primary ad networks to which the lions share of the ad revenues goes to in the first place. Companies like WhiteOps and Moat already do a great job of fraud detection when an advertiser is not buying from one of the popular and safer exchanges.

I applaud your conviction, but the problem with advertising is not solved by attempting to de-throne Google and Facebook.
