Edge, Bing, and Safari do not have majority market share. It would still please me to see these companies broken up. They have their own obnoxious and/or harmful practices that are the result or of attempts to be monopolistic.

I would be surprised to learn that MS does not have majority market share in desktop OSes. Windows still seems to be the default choice - Mac OS and Chrome must be tiny in comparison?

Edit: Windows is 73%, closest is Mac OS at 15% (which was way higher than I expected) https://gs.statcounter.com/os-market-share/desktop/worldwide...
