The problem with the author is the idea of lumping together some good reasons to avoid Brave and some really bad reasons. The idea that the company behind brave depends on ads for revenue is good reasoning, the fact that they have a volatile cryptocurrency to use as payment is another. But when you mention that the founder is a bigot, or that he was associated with Peter Theil, or that they CONSIDERED a shady ad practice are not really reasons to avoid the product.
In the end, you want to have some competition in the browser market (that means not using the same base browser with a skin and some features). I would recommend Firefox over Brave for that reason alone.
