Is there a term for this kind of response?

Its kind of obvious that not everyone will use it. However, not offering it when its somewhat trivial to do so seems like a no-brainer.

I agree that AOL and most other services should offer 2fa. However, I disagree with the parent that the situation would not have occurred if AOL did offer 2fa because the subject in question would still be unlikely to use it.
