We deliver exactly what we advertise; users can enjoy the default ad-free experience, or opt-in, earn, and support content creators across the Web. Nowhere in our marketing or elsewhere do we suggest you can anonymously receive cash from companies like Amazon, Twitch, Walmart, etc.

You don't have the ability to offer private money collection and your advertising should reflect that.

He just said they don't advertise the ability to offer private money collection. Are you claiming they do? If not, then it would seem their advertising already correctly reflects this fact.

They claim to be a privacy focused browser that can pay users via cryptocurrency. Yet there is no point to pay via cryptocurrency when there is no privacy for receiving it.

As I understood it, they claim to be a privacy focused browser that distributes some sort of currency-like tokens to users, which the users can then distribute to websites they want to reward, or optionally pay out as cryptocurrency to recipients that may (or may not?) be identical with the users themselves.

That this optional payout requires identification seems to be A) a legal requirement, and B) an implementation detail of second-rank importance in the grand scheme of things.

Feels far-fetched to get one's knickers in a bunch over stuff like that not being at the forefront of their marketing.

Knickers to you may be outer garments to others. This browser has made a habit of asking users to interpret their actions "the right" way.

Look, maybe this is a good idea, and it is the future of getting people to pay for stuff like news or software. If so then they need someone who understands that vision and can project it with confidence. Right now I have no idea who runs Brave or what person I would look to for understanding their goals. For such an innovative concept you really do need a visible delivery vehicle with whom people can relate.
