> only one of them gives Apple a cut of $6.2M. Every other possible way gives Apple a lot less.
I'll assume good faith and assume that's not a lie, just a misunderstanding. The correct understanding is that the $.50 is a flat fee per install, and Apple's share increases as the price decreases.
If you sell the app for $.55, Apple gets all ten mil. If you sell the app for less, you owe Apple even more than users paid.
The headline is true for the 99% of apps that cost a dollar or less. If they succeed and make ten mil, Apple takes at least 62%.
The expensive apps that would pay less than 50% to Apple are the edge case.
