The difference is that Microsoft doesn’t just give you Edge as the default, they actively try to get you to switch to Edge if you’re using something else, with random notifications, pop-ups in Settings, making it harder to switch to other browsers, making browser links opened by the OS (i.e. search bar, help) open in Edge, etc…

> At least on Windows it is trivially easy to use a different browser and set it as the default.

No, it's not. On 11 at least, any link that is part of the OS (or at least modern parts of it) will still forcibly open Edge, including anything you search in the start menu. It's not possible to change this without third party software.

For a while...

I'd also prefer my OS not choose a religion for me either :)
