This goes both ways for people. I switched from Mozilla to Brave when the latter first released because to me Mozilla's political positions seem at odds with an uncensored and privacy focused browser. I actually support universal marriage equality but don't consider it relevant to why I would choose a browser.

I can't remember all of the details but Mozilla made a blog post regarding 1/6 and their commentary didn't align with a browser that would try and protect users from state, NGO and "just research" edu adversaries.
