What's the problem?
Unlike the Microsoft episode, its not a single market. Android has a greater share of the smartphone market than Apple. If you don't like it, there's other, bigger fish in the sea.
Apple are taking a gamble .. that a closed controlled market is better than a free open one. The fact that there *is* a free open one .. and it is able to take Apple on, means that we have a bit of healthy competition.
If Apple loses developers, and loses significant market share then it will change its (i)tune. Its not a monopoly. Let the market decide in this case.
