You are sore losers! (Score 1)

If you really care about a company whether they are a client or not you should have submited them a list of reasons to choose your product over the competitions. If as an answer to their RFP you chose to highlight the various inconsistancies with microsoft products you could have already made your case to them instead of waitig until their judgement to cry foul. More times than not products are chosen because of what a support staff feels comfortable with rather than the best solution. If you made your case to them initially and they choose to ignore MS's lack of end-to-end security then there's nothing you can do.
