I'm surprised that Gruber doesn't mention the fact that Apple is now in the habit of announcing products or features 6+ months before they ship, both software and hardware (not talking about things like the iPhone which have to be submitted to the FCC). And sometimes, they never ship at all (see AirPower). This would never happen under Jobs.
Also, while Steve Jobs straight up lied in order to protect future announcements (i.e. 'we're not making a video iPod', Tim Cook will say things like 'we are very interested in the AR/VR space' for close to a decade before announcing any products).
