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.
Heavily doubt it. Google wants people using Chrome, not anything else Chromium-based. Otherwise they'd also have no issue with Brave, Vivaldi, Opera (GX) etc.
It's like cars, VW, BMW, Renault, Peugeot etc will all compete even though they all (mostly) use I4 engines.
