That's happened to me. I had to google it, turns out there's a physical switch I never used on the side of the phone that enables it and pushed accidentally.

IMHO, these are not good excuses to avoid a clear interface. If the rules are simple and clear, and presented clearly, even the dumbest of the dumb can learn them. Trying to guess and out-think the user only ends up in more confusion.

I think we're mostly in agreement?

When you disable wifi/bluetooth via the control center, pop-up text appears saying exactly what that means. I'm not sure how they could make that more clear. It still may not be your (or my) desired default, but I at least understand the reasoning.

Tiny, wordy, brief text after the button press is not what I'd describe as clear. If you need to add "comments" to a (now three-state) button, it's a sign that the interface needs work.

It's extra complexity in the form of rules added to what was previously a simple to understand toggle button. That it goes against historical norms, reduces privacy, and wastes a bit of power is the icing.
