Last week, I turned on my PC, installed a Windows update, and rebooted to find Microsoft Edge automatically open with the Chrome tabs I was working on before the update. I don’t use Microsoft Edge regularly, and I have Google Chrome set as my default browser. Bleary-eyed at 9AM, it took me a moment to realize that Microsoft Edge had simply taken over where I’d left off in Chrome. I couldn’t believe my eyes.
Google’s monopolistic and often asinine implementation of web standards that haven’t been fully set in stone by the proper internet oversight groups yet, I’d guess?
Check out the history of WHATWG vs W3C, you might get surprised by which side Mozilla is on, or where did the code for Chromium come from.
