It doesn't imply Hackability at all. You are projecting your tech knowledge into hackability. The commercial is demonstrating that a medical app runs on the iPad.
The commercial doesn't repeatedly flash "iPad Runs..." or "iPad does..."
Instead, the theme is the existential (and grammatically incomplete) "iPad is..." encouraging the viewer to complete the subject. Structured such that the viewer will project their own goals and desires onto the object, it intends to instill the belief that each unique idea can be brought to fruition by the device.
In other words, even such biased completions as "[The] iPad is an energy conversion device" are an valid and grammatically correct. Anything which pops into the viewers mind works within the pattern by marketing intent.
As the article points out, Apple's actions are along the lines of "We don't like people like you." The hurt to hackers when their expectations are unfulfilled by Apple may not be so much technical as social. The disappointment is not, "These damn screws," but rather "Hey, I thought you said I was cool."
