Again, though you're making the argument that because one company engaged in unethical behavior that their system is therefore unethical. On that I disagree. I just don't see an ethical argument here. If we're going to say that closed systems, are, in and of themselves, unethical then the biggest desktop and server OS in the world is unethical and the most successful mobile OS (in terms of $$$ at least) is unethical as well.
Arguing that groups tend to work towards their own best interests (which I agree with btw) is fine, but I can't agree that this is somehow bad. Let's be honest here, competition got us where are now. Evolution itself is based on competition. And Android has proven that there can be competition (and all of the good and bad stuff that goes with it) with open systems as well.
Closed systems aren't unethical based on some theory. They've been observed to _often_ (not always, often) end in unethical practices.
Nothing unreal exists.

And by the way, genetic evolution has zero to do with economic competition, other than being spelled out using the same alphabet and sentence/grammar rules.
