No, and it is pretty useless to ask for that.  How I interpret it doesn't really matter, and that page doesn't give legal advice.

You seem to be hung up on mozilla including MIT code in their about box.  There is a big difference between them choosing to include the text, as a sign of good faith, and them being forced to include it legally.

No I don't.
