Bear in mind that at almost(?) every large company out there the mission statement (written or not) is really "Our Mission is to make money for our investors and the executives who were able to negotiate their own contracts and who control how we do business. We make money primarily by (selling products|providing services|entertaining people). Where we can do so without impacting our fiduciary responsibilities, we may attempt to do the 'right' thing - particularly in situations where we can get positive press or customer relations out of it - but that's a preference not a responsibility and may be considered part of our marketing budget." This may seem cynical, but it's basically the way it has to be at any publicly-held company and most privately-held companies that get VC funding. If you tell investors "We're going to put social responsibility/open source ahead of repaying your investment or providing you with profits," good luck finding investors. Entities that put social responsibility, etc. higher are generally called non-profit, not-for-profit, foundation, etc. and I'm not aware of any that could be described as "a big tech company."
