I didn't even notice that the dialog title, "Use this account everywhere on this device", isn't really presented as a question. Thanks for pointing that out.

Windows is full of dark patterns, so I don't really know why I had even a modicum of doubt.

That's not even the title either --- it's just bigger text within the dialog. The actual dialog title in the titlebar is blank!

Between the aforementioned dark pattern with the buttons/not-buttons (they didn't even bother to vertically align "This app only" and the button), the not-a-question "do what we tell you" phrasing, the blank title, and a dialog that's overall around twice as tall as it needs to be, it seems recent Windows is unfortunately full of user-hostile and also disgustingly amateurish WTFs like this.
