I do not think Apple is an exception to the rule that "ALL public companies are out to make money first and foremost". Remember Jobs was outed because they couldn't see his vision? What happened was they then failed and were later sold on his vision bringing them more money so they put him back in charge. So while individuals have a vision, the corporation only sees green. Everything else is a strategy to achieve it. If you believe that, it follows that internet companies sue each other not because they aren't adults, but because patent law is broken and they are, by their nature, obliged to take advantage of it.
