And Chrome beating Edge and Safari is technical, not marketing. If iOS wasn't closed (Apple's market advantage), would Safari be dominant there?
Mozilla had us up to 2010 because Firefox was a better browser.
I'd really like to see how you came to this conclusion. I hate to be a fanboy but I don't really notice any performance difference between the two in daily use, except in some webGL demos.
Google fought dirty back against Microsoft. Microsoft pulled very dirty tactics to ram Edge down the gullets of Windows users. Google used the same tactics as used by a large percentage of installers on Windows: business as usual?
Or Google actually supported Windows 7 users, because Microsoft wouldn't. Maybe Google really needed a browser that worked and was secure on Windows 7 (not Internet explorer).
Microsoft owned the APIs to their OS yet Chrome beat them on their own turf - ouch!
Google owns the largest digital advertising platform in the world and controls the most popular consumer OS, it's hard to beat that reach.
