I don't think this will happen. I think they will just fade away. They are completely dysfunctional now.
Some say it is due to the whole woke movement, and it may be, but really, I see it as due to politics.
By that I mean, politics is nothing but divisive, and if you introduce it into a company, as a corporate culture, you're going to regret it.
IMO, work is where you leave religion, and politics(the other religion) at home.
And Mozilla is paying the price for letting it in.
yes, and forcing out there reasonable CEO for a purity test, long ago.. HELO BRAVE
Eich is not unproblematic, of course (in addition to the anti-gay marriage issue, there is/was also issues of 'covid-scepticism'[1]). And the cryptocurrency stuff in Brave is uninteresting to me (fortunately it's opt-IN though and not opt-out).
And I still think, on the desktop at least, Firefox still has advantages over Brave (and even more so over other Chromium-based offerings).

And yet it's the only mainstream browser for android that support, natively, ad-blocking. Using chrome on mobile is a joke.
The entire Android app was overhauled a while back, dropping functionally and decreasing stability, and has since been pretty much ignored even though it is still missing features and is still painfully clunky and prone to crash. The developer tools on the desktop app were ahead of Chrome but have stagnated, and they're slow to adopt new standards, but they somehow find time to add things no one asked for like Colorways and a VPN.
I want Firefox to get its traction back, but it's hard to cheer for Mozilla or blame Google when I see them twiddling their thumbs like this.
