I installed Brave earlier this week and that’s mostly true. There’s some built in stuff that will show by default, notably the toolbar buttons and the notification style alert on the new tab page for one of those things mentioned, but you can just close the notification and remove the toolbar buttons and you’re set.

That said, I think it’s still in the data monetization market like Alphabet with anonymized tokens, though I don’t remember the details.

Might I suggest No Nag November as an alternative?

I think the greater fear is that anything done against him becomes fuel for the Republicans/conservatives to elect an even worse human being.
