I don't understand how this is an invasion of anything?
Just because Apple is capable of doing something doesn't mean the worst case scenario will occur.
1. Apple could deauthorize all of your iTunes music today if it wanted to.
2. Apple could deauthorize EVERYONE's iTunes music today if it wanted to.
3. Apple could send out a software update to everyone's iPhone that bricks them all.
4. Apple could send a Mac OS X update to package up all your email addreses from your Mac and send them to the highest bidder.
5. Apple could deactivate an app on your iPhone for no good reason at all.
Just because Apple could do something doesn't mean they will. Why aren't you outraged and complaining about #1-#4?

You're right, and part of me wishes they would so we could get this EULA nonsense into court once and for all. Pretty much all software providers want to avoid going to court over EULAs because they are afraid that many of the draconian provisions they put in them will end up being ruled against. So when you say that you only lease software and that the software provider can shut it off at anytime because it's in the EULA keep in mind no provider in their right mind would do that. The case would end up in court and EULAs as they are currently known would most likely be destroyed.
