They have a lot of money, compared to more budget-conscious customers, and they are used to paying more.

Makes for an attractive customer base. I know that there have been a number of studies, that found Apple apps make a great deal more money, per app, than Android ones (I'm sure there are special outliers in both camps, though).

I make free apps. In my case, it has nothing to do with "snobbery." I've just been doing it for most of my adult life, so I'm invested in the platform, like many of us do.

I also enjoy working in a challenging environment. I've learned to adapt.

So, again, why is this distinctive from the natural monopoly that Microsoft attained and illegally abused to restrict competitors from having equal access to their platform?
