The main thing I remember from the era of Gates Is Literally Satan was the browser wars, and how awful it was that Internet Explorer was both free and tightly integrated into the operating system.
Dishonest comparison is dishonest. I'm pretty confident it's actually possible to uninstall Safari, and that macOS will continue to work.
Besides, the integration with the operating system isn't the problem. It's the integration with the only operating system. It isn't monopoly abuse if you don't have a monopoly.
#cough# Safari on Apple devices
