While I understand your argument about IE6 which was shipped with Windows, Chrome didn't have that advantage for a long time - it's only now that Android phones and Chromebooks are shipped with it, but I don't know of a single person who does not download Chrome on their Windows Desktop too - even now when Edge is based on Chromium! Firefox has always been my primary browser (it still is, I'm typing this in Firefox), but say what you may, Chrome has taken the internet forward in many aspects. I work on an in-browser CAD tool, and I can see how vastly better Graphics performance is in Chrome when compared to Firefox for example (and it's just one example).
