I use Firefox because it's the least bad option remaining, certainly not because I believe it's the last remaining ethical web browser. I have no confidence in Mozilla's ethics or mission, and no longer contribute directly or financially for that reason.
I agree with the implicit point. From the ethics standpoint, regardless of what happens at the top, Mozilla's waywardness isn't reflected in the browser, unlike Google's web and user hostility with Chrome (manifest v3 etc).
