I think it's healthy, even necessary, to utterly distrust microsoft (or any large compny, for that matter). And while I don't think it's a-ok to call an individual microsft employee a monkey by name I think it IS a-ok to say any microsoft product is 'written by monkeys' or any other suitable derogatory term.

The way github develops is steered by microsoft-the-company and not so much by it's individual employees. A company, especially such a huge one, is not to be trusted and can (should) be made fun of.
