Mozilla is adopting a ton of the things that were wrong with Brave. Recently, Brave criticized Mozilla's PPA data collection for being too centralized, which implies to me that otherwise, there's a lot of overlap between the two allegedly "private" systems. I don't trust Brave telemetry, but it seems not even they can come up with many ways to differentiate themselves from Mozilla.
If they're different somehow, I would love to know how.
In a way other than accrued trust or distrust, that is. At this point, I don't think Mozilla is owed any inherent trust.
No argument from me there. I didn't mean to come across this argumentative, I just wanted to point it out here because of the context of this post (someone looking to move away from Firefox). And because, to me, ad telemetry still is a black box.
