That's interesting. I thought that everyone was mocking Iron Man for wearing it (people my age wore Axe when we were in middle school). It hadn't occurred to me that this was still probably a net positive for Axe.
On the other side of that paycheck, if producers "just" wanted to make a joke they would simple have a line such as "you are wearing lavender perfume..?" (or something equally silly).
And let's of course not forget them beautiful Audis that I remember well, are 'starring' in every Avengers movie. I wonder when that contract will run out... I searched (duckduckgo) but I didn't get any hits with the information.
