According to my basic understanding of basic economics (FWIW), doesn't this put a hole in the monopoly hypothesis here? [I'm not even close to being an economist, but I've taken a basic class or two.]

I looked at their 2017 financials, and they have revenue/ expenses broken out for many many brands and regions. There are huge variations in margins due to what it seems like to be growth expenses. Some of what i'd think to be more mature lines at first glance to have crazy good margins.
