"I don't accept that."
Addressing the strongest possible reading and all that.

Just read "common sense approach" as "that makes sense to me" and it fits perfectly. As for common sense, ask random people on the street what they think turning something "off" means. Do you think you'll find even ONE person who says "oh, that probably means it'll stay off until I change location, or until 5 AM, whatever comes sooner?". That's the elephant on the couch.
The use case of what you or most would find convenient, and would prefer to have available with one touch instead of more, is completely orthogonal to what all of this is about -- the common sense of what any normal person who isn't bent on defending Apple just because would respond with 1000 times out of 1000: of how to read UI in this case. Consider it a use case for the UI, and to even suggest just one person actually has the use case you declare to be such a majority they must be catered to without any further investigation (e.g. if the majority is wrong, that should strengthen, not weaken your resolve) truly is ridiculous.
