I have to say the author's attitude does not come off particularly well in this post, at least in my opinion. Just seems rude.
What I would say, however is "rude" is attributing malice when there is a perfectly reasonable alternate explanation to a story.
That's really what I take umbrage with; our standards for truth should be higher than the insinuations of a MSFT intern with no clear evidence, and a total lack of the net community as a whole even to consider alternate possibilities.
