I didn't say either of these patched the kernel (one is in userspace, the other one is, well, you don't know where it since I didn't describe one) just that the difficulty and complexity of some potential exploit doesn't mean the exploit isn't important both to Apple and end-users.

You were arguing that some of Apple's mitigations are only aligned Apple's business interests and not those of end-users. I don't think you've said much to really show this is true, other than in your specific case. Not wanting the phone to be jailbreakable, to provide some assurance that when you buy an Apple phone, it's running Apple's software as designed by Apple and that it can't easily and surreptitiously replaced with something else is a perfectly reasonable consumer expectation very much in line with what Apple explicitly sells and promises of the product and services it comes with. The 'for no reason' bit just seems obviously inaccurate.
