For their innovation they were rewarded for being first to market with a good product and win a very large market share which they profited from for several years and are still profiting handsomely, and managed to build a powerful brand that will help them to continue to help them earn abnormal profits in the short to medium term. You're saying that Apple deserves to make abnormal profits for many more years (15 or so more or however long their patents last).
Profit is a feature that exists not to serve the entity the profit goes to, but to serve society at large, to encourage services to be provided, to encourage innovations. You're saying Apple should be awarded additional abnormal profits above the monopolistic competitive profits they're already generating. Is their current situation not enough to have encouraged Apple of 2006 their innovations? I doubt it. If Steve Jobs was told patents only lasts 5 years, I'm sure he'd have gone on to lead Apple to invent the exact same things. If that's the case, what's the point of giving Apple additional monopoly protections, at the expense of society at large, due to the increased prices they must pay and reduced innovations they will receive in return (since other companies are disincentivized to innovate on top of what Apple has invented)?
Is it because of how Steve Jobs would have felt? He's a great man, but we should not be reduced to living in his shadows forever. We must stand on his shoulders, for that is how humanity have advanced ever since the first hammer was passed down from father to son.
