Your comment about 'You don't get to freeride after X years' is perfectly reasonable if google's goal is to stop contributing to the open parts of android.
I am not disputing Google's right to do whatever it takes to compete, or that there is somehow something morally wrong about that.
I am disputing the canard that 'Android is open' when really only a part of it is, and that part is not what most people think of as Android.
I do thing there is something morally wrong with perpetuating this misleading idea, even though it furthers Google's PR goals.
I know that corporations mislead us all the time with communications that are technically true but pragmatically false. I realize it may be naive to expect different behavior, but it's certainly not going to stop if it isn't called out.
