Apple isn't a person, they are a company, and their primary goal is to make money, not be nice. In recent years their R&D budget has topped $1 billion. I don't think it's far fetched to assume that they are going to extract everything of value, patent everything they can, that springs from that investment. To do otherwise would be a disservice to their shareholders.
_I_ don't like what Apple is doing, but they are following the current rules of the game. If you don't like the outcome, then work to change the rules. Expecting Apple to play nice is unrealistic. They are going to do whatever is in their own best self interest. That's how our economic system works.
A large part of the problem is that most people aren't even aware that there is a problem. That's why public discussion such as this is valuable: if enough people are aware, then change is possible.
