The other way to look at this, is that Apple winning will generally cause the IOS ecosystem to really shine more than it already does. I think walled gardens for IOS is a good thing. And the competition will cause people to leave apple if they are better at doing something than apple is.
Nah, because after a while, you get into a dependency point of no return, or a point without an easy return.
If Apple win this case, Apple, Google & Co. will be legally strengthened in what they believe is right to do.
Think a bit further, few years from now, Apple Ecosystems all over the place, all nicely crafted together, centralized to Apple Servers, wonderfully working and comfortable walled gardens, and you in a great position to pay that all.
And somehow they decide to, or "accidentally" disabled your AppleID, maybe because they disagreed to something you've said or did, this will...
... lock you out of your house
... lock you out of your car
... lock you out of your garage
... lock you out of your bank app and from quick accessing your money
... maybe even lock you out of identifying yourself, few countries are already thinking about "virtual ID and Passports"
... lock you out of healthcare(e.g. from accessing your EGC recordings)
... lock you out from all devices you own (hold a moment - did i really say "own"?)
... lock you out from ANY app you paid for, that build on their APIs
... and much more
and a lockout also means deletion of data in some way...
It's not fully fictive, we are already getting into this dangerous centralized level of corporate control.
I mean they tried to delete Epics Dev Account, and i bet that all devices associated with it would have gotten into an unknown, maybe even unrecoverable state. Just think about it!
