> Microsoft's penchant for co-opting others' ideas, then twisting them to their own ends (e.g. "Embrace, Extend, Extinguish") leads many to scrutinize the CodePlex Foundation more carefully than they might one created by a different company.
I'm not altogether sure that's really the mechanism in play here.
I tend, myself, just to apply Clausewitz' rule to such situations ("Plan not for your enemy's (apparent) intentions, but for his capabilities", or, in short, Assume Bad Faith, to riff on a Wikipedia rule -- why do you think they need to *specify* that's a rule?), and I suspect something similar, if perhaps not so formalized, is what drives a lot of people's opinions; a perception that a company is unusually *good* can override it (viz: early Google, though perhaps they've worn out their welcome).
