Looking into this only briefly, it didn't take long to find a lot of very questionable decisions made by Brave:
1. They're positioning themselves as both an advertiser and a privacy advocate[1], which strikes me as more of a strategy for bootstrapping revenue than a trustworthy moral position. The entire point of crypto micropayments is to pay for content with crypto rather than attention/privacy. Why should I view Brave's ads rather than the other ads on the internet from advertisers who also claim their ads respect privacy? The fact that Brave has decided to get into bed with advertisers at all shows they're committed to profit, not to users: micropayments are just a way to diversify for Brave, which will quickly fall to the wayside if it fails to provide the revenue they want.
2. The entire concept of a Brave Verified Publisher stinks. It positions Brave as a censor. If this system takes off, then suddenly Brave has control over who gets paid for content on the internet, and can censor content they don't like. And this isn't hypothetical, they plan to do this: their TOS[2] explicitly contains a code of conduct which contains a long list of things they will terminate your account for: they promise to use their power as censors to enforce of US copyright/patent law and also a wide variety of subjective social norms. This also shows their commitment to being an advertiser rather than an application that serves users: if you're serving users then you let them pay for the content they want to pay for, but if you're serving advertisers, then you can't let advertisers brands be seen as supporting questionable content.
3. BAT based in Ethereum seems to be basically a way to ride the wave of cryptocurrency hype while still positioning themselves as a central authority/middleman. If they weren't trying to position themselves as a middleman, they would just make the micropayments in Ether directly, or better yet, in a cryptocurrency that doesn't have a history of forking the blockchain to fix an bug in a major users' contract[3]. If they weren't trying to ride cryptocurrency hype, they'd just allow micropayments via a much-simpler-and-more-reliable REST API or similar since they're already the central authority anyway.
I don't think we can trust Brave with our privacy or attention. I don't think we can trust Brave with the decision of who gets paid for content. I don't think we need Brave as a middleman to pay content publishers. I don't like the state of how content is paid for on the internet, but I don't think Brave is the solution.
It's disappointing to me that Wikipedia has decided to associate their name with Brave's. A big part of why I respect Wikipedia is their long-standing policy of keeping independent from advertisers, and it seems naive of them to have not realized that Brave is an advertiser. I can understand why Wikipedia has made this decision, but I still think it is a compromise of Wikipedia's values, and I hope they'll reverse their decision in the future.
