Don't forget Apple. They told Apple that they would not use this key in certain ways, even though they do.

I don't see the problem with calling this "illegitimate". Jailbreaking so you can sideload apps is legitimate. Somehow cracking Apple's verification so you can sign apps without their involvement would be legitimate. But signing up for an enterprise account and then using the keys they give you as part of that in ways they tell you not to is, I think, legitimately illegitimate (ahem).
