I'm curious if the Microsoft of today has learned its lesson and changed its ways? As an outsider now, I see lots of positive things going on such as acceptance of other platforms (especially Linux), open source activity, etc. Is Microsoft a good place to work again for a hacker (who doesn't play politics)?
