Even if it is an increase in price (debatable), that doesn't mean that Apple's distribution monopoly is responsible. I expect that prices on Android have done the same thing, and Google doesn't even monopolize the distribution there.

The exact same thing has happened in the AAA games market (see EA, Activision, or Jim Sterling's many videos on the topic) which is provably nothing to do with "Apple's distribution monopoly".
