It is more and more clear that to accept Apple's security (which seems to be getting better, but obviously still insufficient) I must also accept Apple's commercial limitations to the use of a device I own. And I suppose that the dividing line between the ability to exploit a vulnerability and to 'have control' is a sliding scale for every user: one man's 'obvious' kernel exploit is another man's 'obvious' phishing scam.
It is not a new tension, but it does seem the stakes on both sides seem to be getting higher and higher - total submission to an onerous EULA vs total exploitable knowledge about me and my device. Both sides seem to have forced each other to introduce the concept of 'total' to those stakes, and that is frustrating. More-so when it's not yet clear which threat is greater.
