Just kidding. It’ll be $59.99 at both stores. There is, practically speaking, no competition in the retail space either.
Nintendo Switch titles tend to cap at $50, not $60.

It doesn't change the underlying point, however.
So don't, then. Apple doesn't force developers to make iPhone exclusive content. And consumers are not forced to use only one device. This whole issue is merely developers complaining that they want cheaper access to the most lucrative markets. It has nothing to do with consumers.
Your reasoning is valid if Apple happens to be not so big player or if Apple has many alternatives. Between iPhone and Android, do consumers have any other choice? Between Windows and Mac, do consumers have any other choice?
