1. Hype driven people who crypto ads work well on.
2. Privacy driven tech people who are pretty much non-monetizable.
Self-service ads are useful for small to medium-sized advertisers who want to target specific niches with pinpoint accuracy. If Brave's whole thing is that they protect your privacy from targeted ads, and also they lack the scale to be useful for non-generic ads, then I'm not sure any of this makes sense.
I don’t like everything that they do, but I respect the fact that they are actually trying things.
Saying flat out that a privacy driven tech person wouldn’t use brave at all is reflective of the counterproductive discourse within the community, where every tool in existence fails someone’s purity test. Firefox, ddg, protonmail, etc have all had their scandals.
