Now I'm starting to wonder if you even read the "No Output" letter and understand its implication? You essentially called a bunch of Microsoft employees productivity drains on the rest of the company. The fact that you think a cancelled project means it is the same as DEC's "No Output" team likely means you don't understand what the "No Output" team even was at DEC or the implication for the people within it. You absolutely do need to present proof of what you're saying, because it is a serious charge for both Microsoft and those employees alike.
