While this may be technically true, the reality is that when you take $10 billion from a company there are strings attached. Consultation on a decision of this magnitude is one of those strings. You can choose to push ahead anyway after this is done but dropping the news on them 1 minute before you pull the trigger is unacceptable and MSFT will go for the throat here. You can't be seen to be a company that can be treated like this at MSFT level when you have invested this much money in any org.
