replying to the 1st point: it seems to me that you don’t really know the anarcho-capitalist movement. We DO NOT embrace anarchism and we all think the “anarcho-capitalism” term is bad, but it’s simply the one everyone else uses to refer to us, and the one Murray Rothbard (sadly) came up with. We are against the existence of the State, but this does not makes us anarchists and we don’t claim so.
Firefox does some nasty stuff too. One could argue every major modern browser does, and sadly it’s almost true. However some like Brave (has done bad stuff in the past) and Ungoogled Chromium seem more trustworthy. Read: https://spyware.neocities.org/articles/firefox.html
