Microsoft's communications are always so unnatural. Why does Microsoft maintain this corporate communication style? Every announcement event is just so uncomfortable.

These are clearly executives on stage whose asset is leadership, but they insist on injecting unnatural banter & distracting idioms. What corporate communications person hears a marketing manager talking about "photons" w/r/t kinect and doesn't cringe?

Is it just momentum within a communications team? Is it that they can't abandon this style because it's so deeply embedded in their communications team's culture? Or does this style actually work on some market segment?
