There is one competing phone platform with a store that has conveniently decided on identical fees. It's a duopoly. But also one where you can only shop with one of them.
The comparison is this: Walmart and Target are the only two stores that exist. They've also basically agreed to set the same prices on everything. And once you buy from Target once, you must buy everything else from Target too, and if you want to switch to Walmart, you have to throw out everything you bought at Target.
