Apple has taken the posture of the 800lb gorilla with a questionable legal maneuver, leveraging a patent systems its competitors were happy to support to keep smaller players down until it was used against them. And Apple can still lose the next move in this legal chess game if Google takes them on.
This is very different from for instance the Microsoft of the '90s that had so much market power of its own it could dictate terms and kill competition simply with money and threats.
That was a real 800lb gorilla. Apple is playing a very dangerous game by faking it through dubious legal tactics. But one court decision that doesn't go their way can completely kill that.
Also the fact that Apple is the most valuable company in the world.
Yeah, and Apple also isn't the 800lb gorilla when I can fly around on magic monkeys.
Just as wrong is the argument that "Apple has made a lot of money, so they don't need IP protection." The alternate universe where Apple has no patent protection on its designs is a very different one from this one, and one in which competitors would have been outright duplicating a whole lot more.
Also, being the underdog or the overdog should not affect one's property rights. If a tiny small company does/does not deserve protection, then so does a big one.
