That doesn't have much bearing on the cost of switching considering most of that friction is borne of investment into a particular platform and the intentional difficulty in migrating to another platform. This is the central caveat of walled gardens, the walls do not only serve to keep unwanted things outside, they also serve to keep you inside.

The analogy to a company town is apt. When you embarked for a town, both AndroidLand and Appletown were the same distance away, but now that you have settled down the prospect of migrating outside is considerably more difficult.

What high cost of switching? There are hardly any popular iOS only apps or popular apps that people paid for instead of buying a subscription that works cross platform.

As far as media that you bought, music that you bought on iTunes has been DRM free for almost a decade.

Even with movies, you can blame the lock in on the studios that don’t participate in “Movies Anywhere”. Any movie from the participating studios that you buy on Prime Video, Google Play, Vudu, or iTunes is automatically considered purchased on the other platforms.

Most of the money being spent on the App Store are from in app consumables.
