Maybe but it doesn't affect the ad-blocking abilities of Firefox and uBlock Origin. It is a legal document, not a technical document.

If you want to go with ethics and trust, I am not particular fond of Brave practice of replacing ads for some shady cryptocurrency (BAT). You don't have to do that, you can just use it as an adblocking browser, but if you don't care about these things, the news of Firefox updating some privacy policy shouldn't affect you too much either.

Anyways, both Firefox and Brave/Chromium are open source, you can see what data is being sent out, and there are forks.

And to make things clear, I am not really a fan of Mozilla direction, I just switched because Firefox became better and Chrome worse in the last years.
