Microsoft has decided to creatively reinvent themselves as a company, pledging to not do so much evil any more, for a change. Or at least they seem to pledge to implement some of the things they have been forced to by various antitrust rulings against them anyway, and call them the "Windows Principles". Ahem.
So, for example, Microsoft wants to tell you that it recognizes that "Ultimately, end users are free to choose which software they prefer to use.", or that "Microsoft will not retaliate against any computer manufacturer that supports non-Microsoft software.", and even "More generally, we want the developer community to know that it is free to develop, support and promote products that compete with any part of Windows."
I have thorougly enjoyed Microsoft's use of the verb 'to retaliate' all over that piece of corporate propaganda. Priceless.
