I happen to know jwz personally, and he knows Mozilla intimately: he founded it. His dislike of Mozilla is pretty much the same as mine, and he is neither “anti west” nor anti liberal. We dislike Mozilla because it has lost its way from being a FOSS browser maintainer and a booster for & steward of an open web.
And I’m not “anti-West,” I’m anti-capitalist, anti-settler-colonialist, and anti-imperialist; and those happen to be things that “the West” presently embodies.
