Isn’t that what every company that sells technology does—build demos and showcase uses in order to provoke the imagination and motivate sales? No company is perfect, but what Microsoft is doing here is hardly unusual.

Microsoft is on a roll, on a roll at repackaging open source efforts and branding them, and then saying they made it.

I mean this in the best possible way, but I don't think you're using "altruistic" correctly. Altruism is "showing a selfless concern for the well-being of others." I think you're looking for "naive," and Microsoft is some combination of cynical and manipulative.
