For example, "links clicked on within the Windows Mail app will open in Microsoft Edge" regardless of any 'default/preferred browser' setting. Sounds like a pretty hostile user experience, to me.
Unfortunately people are better at copying Apple on the annoying shit like this than at the stuff they're actually really good at.
Windows had this concept for a while (and still has) and is just intentionally ignoring it - that's definitely hostile.
Even third party apps that build in their own chooser in iOS tend to be only Safari and Chrome... :rolleyes:
Windows users may complain about it, but they remain a largely captive customer base, as far as I know. Especially organisations. They rarely consider switching to a different OS, regardless of what Microsoft does.
