Is that the same Brave that injected their crypto functionality into the HTML of sites downloaded over HTTPS, like Twitter? I don't trust them
Also re MitM'ing for crypto mining: I was never in favor of pushing Brendan out of Mozilla for being a supposed right-wing nut, but I am not surprised either to see that, given free reign, he _is_ a right-wing nut.
So you're saying their Privacy Policy is a lie:
"Our company does not store any record of people’s browsing history."
