Word is that this was made by somebody inside Microsoft, and that they're in hot water now that this has come out.
If true, that's foolish. Denying the reality is a move from weakness. As is using power to suppress the discussion. Seems like a poor idea to punish people for being talented and expressing dissenting opinions; the obvious lesson for employees and prospects
to draw is that Microsoft would rather have a mediocre monoculture.
Of course, if that's what the execs want, it's easy enough to get.
