I don't think there's an easy answer. Any central repository managed by the company (Apple, Firefox, Google, etc) is subject to the same thing. At its core, FF is a solid privacy browser to start with, but add-ons are needed for any of them (even Brave). People pretty much have to help others individually to get access to the tools.

Ladybird?

I guess Tor Browser is their only option. I like Librewolf, which is a fork of Firefox focused on privacy, but it uses the same Mozilla add-ons. Not sure if there's a way to circumvent this kind of censorship.

Good question.

While Mozilla might seem virtuous, they clearly have motives.

I'm trying to remember what other news came out recently that seemed to highlight the political stance of Mozilla Corporation, I think it was related to not allowing payments in cryptocurrencies, generally.

Seems that for an open source project, they grew pretty large and like many browsers that come preinstalled with search engines, tailored for different locations, they surely have backers and financial interests these days.
