And they really aren't fighting it very hard. The last thing they fixed was a remotely exploitable hole which, when combined with another bug, let remote root a phone without the user's knowledge from a mere web page.
The fact that a remote root vulnerability existed means Apple doesn't care about jailbreaking? By that logic OpenBSD doesn't care about security because they've had two remote root vulnerabilities.
Oh, I see, but that doesn't demonstrate his point that Apple isn't fighting jailbreaking very hard. For that he would need an example of a vulnerability that Apple didn't fix.
No, I mean that the last time they "fought jailbreaking" was by fixing a horrendous remotely exploitable security bug. Not exactly a stunning example of fighting jailbreaking.
