All this talk about Mozilla's political views, what about the political views of the Google leadership? Why do they get a free pass? I think blaming the politics is a just-so story. I saw everyone adopt Chrome over the years since it came out, and it had nothing to do with the leadership of the Mozilla foundation, or Google for that matter.
What happened is much simpler: Chrome worked better than Firefox, most of the tech people switched to recommending Chrome, and it was bundled with a lot of software and advertised on the Google homepage. And nobody ever switched back, and they started justifying why in various ways.
