> What's wrong with Apple insisting that developers not jailbreak their devices?
It's my device and I have the freedom to do with it as I wish. EFF goes into a lot more detail if you want to read it.

I won't sign it, and and I will sign a petition, and I will warn other developers about it. It's my right to point out bad behaviour and to complain. You presumably accept this since you just posted a comment complaining about something.
