“Minor” nitpick: there was a communist revolution in 1917 in Russia and Ukraine. But after Lenin came back from western european comfort, seized power and murdered all the revolutionaries with the help of his friend Trotsky, there was no communism afterwards, only State capitalism.

I mean it makes sense that the majority of the remaining population has decent standard of living when you have slave work in the gulags… under that standard, nazi Germany also had good economic standards thanks to the working camps. That doesn’t make any of these approaches good.

Yes, that’s precisely the problem. This is a traditional evil startup doing open-washing/p2p-washing. A blockchain is in 99.9% of cases the wrong approach to the right problem. And even when a blockchain is an acceptable solution, advertising remains utterly unacceptable (buying into people’s minds and opinion is the opposite of democracy) and a single for-profit entity having power over what’s considered a public utility (a blockchain) can only lead to bad outcomes.

Brave Browser has had many shady practices over the years, and is owned by the ad industry. They have repeatedly shown their commitment to dubious, user-hostile practices for their benefit. See for example a few examples listed on their wikipedia page (among others).
