Brave seems well-intentioned but really dodgy to me. In addition to the other issues that have already been raised, they were initially collecting money on people's behalf without their consent or knowledge [0]. The problem has since been resolved but their handling of it at the time put me off them for good.
Replacing ads with their own ads, running a cryptocurrency within the browser. I don't want microtransactions to view sites which I feel like is what Brave is hoping for in the future. I mean, microtransactions are the name of the game in cryptocurrency but doing so for online content is especially egregious.
When able to do so, many choose products based on principles regardless of how they use them specifically (hypocrisy and comparison of evils notwithstanding).
