There's no agenda, just proper reasoning. Think about it in terms of Bayesian probability: it's a cryptocurrency product, and pretty much everything in the crypto space is a scam, so right off the bat when you hear about Brave, before you even know anything your prior probability that it's a scam is 95%. Then they got busted 'keeping the money' and not telling the creators, and the posterior jumps to 99.5%. I know they mostly fixed that, but at that point the trust was gone and it's not worth anyone's time to give a second chance.

It sucks, but at the same time, if you're going to be an honest actor in crypto, you better cross every t and dot every i, because bad actors are everywhere and so smart people just assume bad faith and are arguably correct to do so.

The reason that Brave doesn’t get a great rap around here is because it trips the sketchy detector. They make a marketing image of themselves as the protectors of privacy and whatnot and then the browser includes (or included) a lot of features that seem to go contrary to the stated mission.
