I think the catch is that if you installed chrome and use it, you won't see those prompts, and if Microsoft changed teh default away from chrome against your wishes, you probably do want to be notified of the change.

I can opt out of googles nags by just not installing chrome, I can't say the same for edge on windows.

I expect the prompt is there to neg more than nag. I presume the only people who click “no” on the “Are you sure?” prompt are unsure as a result of the prompt itself. In other words, the role of the prompt is to make them second guess themselves and feel inferior to the OS. “I better just not mess with it, I guess.”
