Google makes money by collecting behavioral data generated by its users, which it then uses in the form of raw materials to create products for its actual paying customers: advertisers.
Whether you're using an ad-blocker or not, you're still contributing to the advertising machine by using its products, you can't stop Google from crunching your personal behavioral data on their platform.
I have no interest in Brave and I still use Google products (for now), I just wanted to point out that what's really happening is a bit more sophisticated than you may think.
