You can down vote me all you want, but I feel zero sympathy for Microsoft. If their app is being blocked from YouTube is because they deserve it. Google has all the right to choose which third parties can access YouTube. Microsoft is in no positing to criticize the actions of other companies.
I'll take Google over Microsoft anytime. I believe there are no absolutes everything is relative, everything depends on the context, on our scale of values. Personally I don't care about such concepts as open or evil. If the actions of a company are illegal they should be punished. If they are not but they ought to be, you can try to build enough consensus to legislate on the matter.
I personally feel more wronged by Microsoft than by Google, I've never been forced to use Google products. The pervasive dominance that Microsoft still holds on the desktop is poisonous. Until I am free to choose or not to choose Microsoft products I will feel wronged by Microsoft.
