I guess there are some things that distinguish this though - it's much easier to go to a different supermarket than to switch app stores, given there's no hardware compatible with both. It's also potentially easier to have your product in multiple supermarkets (assuming you don't agree exclusivity), you just have to scale up your manufacturing - on an app store you need to produce a different version. That's complicated by things like React Native and the fact that digital has no replication cost at all once written though. There are also more supermarkets vs 2 app stores, though they probably all do the same thing so I'm not sure how much that matters.
