My thoughts exactly. I really hoped there was something I missed about Brave, but it seems they are worse than I thought. Not just position itself as the middleman to take a cut from ad revenue, but trying to profile the users as well? All this with a PR crap of rescuing an industry. Call me old fashioned, but I would prefer my browser displaying documents.

I think what he's saying is that they do the inferences from localhost, more or less (see e.g. https://www.microsoft.com/en-us/research/publication/serving...)

There are a number of proposed systems under the rubric of "privacy preserving advertising systems" and they are very different than what ad-revenue driven companies are doing today and similar to what he is proposing above.

I don't think most ad-revenue driven companies claim that these things are done locally, which seems key.
