Of course it does. With a given number of resources, more options needs to be supported means less resource spend on each one.
The core issue here is whether governments should control how iOS is designed and which part of iOS.
Furthermore, it can be argued that forcing iOS to be more like Android decreases competition. If you want a more open platform, just get an Android phone.
That's Apple's core issue, maybe.
Now, look at it from the perspective of a sovereign market. Their core issue (a-la United States v. Microsoft Corp.) is how much they are willing to allow while admitting market access. In Microsoft's case, their manipulation of technical capabilities was considered illegal monopoly action. Apple is treading on the exact same ground with Safari and going even further in the case of the App Store - corrective litigation was an inevitability.
Apple ultimately doesn't have to abide by the EU's decisions if they don't intend to intend to access their markets. Governments[0] already[1] control[2] so much[3] of iOS[4] though[5] that it's kinda a moot point =)
> Furthermore, it can be argued that forcing iOS to be more like Android decreases competition.
It can be argued that competition with Android is not what iCloud, Safari and App Store regulation is about. It's certainly not mentioned anywhere in the DMA or Japan's equivalent legislation.
