You don't naturally have any expectations of a right to run whatever code you want on a phone. There is nowhere written in law or regulation that you have such a "right". So there is no such right to give up.
Apple enters into an agreement with you to give you a phone with certain capabilities. Control of what code is executed by the phone is not included in your capabilities. End of story.

Plenty of things that you naturally have a right to do aren't written in a law. Is there a law saying you can browse and post on hackernews on your computer?
I did not sign a contract relinquishing my rights to execute whatever code I like when I purchased my phone. Does one have to do that with an iPhone?
If you do, shouldn't it be called an applePhone, not an iPhone? If you cannot control what code is executed by the cpu, it is really more Apple's phone than your own.
