Jan van den Beld has a great post that exposes the hypocisy of the anti-Open XML community. An excerpt from his post:
Many views should come to bear on decisions made in standards bodies. It is ok to represent your views. It’s healthy. But it seems inappropriate to me to tear down anyone and any organization who disagrees with you through allegations of corruption. It is time to move on, particularly when you are throwing rocks while living in a house with LOTS of glass. Let the voices of 61 countries around the world stand and stop the attacks, if only to stop highlighting your own hypocrisy.
