I would love to hear that they did it. In long term all of us will only benefit from this. Think of it that way, nowadays apple device are fine but lots ot the people are unhappy with them, then they figured out the jailbraking... and improve their iP* instead of buying better device. Lets imagine apple has really sealed the iP*. Competition will listen here and there what is wrong with apple and release their own product - what apple can do then, dop price or improve the device.
Nowadays, honest good customers are betrayed - either they go to the dark said and jailbreak, or will grumble, grumble ... and wonder year by year why apple do not listen to them.
