I don’t recall any new controversies with Brave similar to that, but that said, there’s not much of a reason to use anything other than Safari anyways. You’re forced to use WebKit, and using something like Brave (which tbf is probably one of the better alternatives despite their history) only increases the number of parties you must trust, while mostly just being a reskin of Safari.
If lack of good ad block (e.g. beyond DNS) is a deal breaker, Brave seems to be the only open source option. Otherwise a good DNS server and adguard should get you most of the way there on Safari.










Vivaldi is chromium… It’s also not FOSS. As with most the other people in the comments, I’d suggest Librewolf, though I’m looking into going back to regular Firefox with a custom user.js for added security.
