Most every major company tries to build a walled garden. Apple does so via apps and services, services like netflix do by making sure you can’t watch shows on any other service (arr!), or even something as simple as cordless tools that have proprietary batteries and chargers where it gets really expensive to have to buy different batteries.
Finally. We all about to see better prices and more features. If this ends in lower app store fees, its a massive win for every app company in the world!
Well, they did get them to switch to USB-C, so I'm not holding my breath, but I do hope that this will lead to more interoperability. I'm tired of Apple making Android/non-Apple users feel like second-class citizens.
