100% agree. I also observed that some time ago, many platforms would use interoperability as a growth tools (ex: Facebook with 3rd party apps/games, Google with the 3rd party cookies, Apple with iOS APIs) and then, when they reach critical mass, they would close down and become closed gardens. Watching all the preparations for the Open Banking regulations here in Brazil (still not in place fully). The concept is sound, as the data belongs to the user, not the bank/platforms, so banks/platforms should enable this data to freely flow (on the user command) to other platforms. I think forced interoperability might have a good effect on that world, and also it seems to foster innovation by lowering the barriers of entry but I don't really know the effects on investment and VC money when you eliminate an effective competitive barrier.
