Here's a Microsoft quote on Mozilla:

Microsoft has a job vacancy for a director of open source strategy - what does this mean for Microsoft, open-source and consumers?

t seems we’ve arrived upon Microsoft open source. In the last couple of years, whenever there was discussion of Microsoft’s open source projects and efforts such as CodePlex or Port25, there was typically the standard open source response: it’s not OSI-approved; it’s not real open source.

One minute ago Microsoft made one of its first "open source" moves under the new Microsoft Reference License: the team in Redmond announced they'll make some .NET libraries available. I say "open source" because to me, open source means you can easily access a .tar or .zip of the code. Microsoft's effort is a bit more cumbersome.

Novell is working with Microsoft to help Microsoft cooperate and contribute to open source projects under open source licenses, and sticking with the existing standards to do so. Keen observers of the tech industry might note that this is a bit of a rarity, but it’s something that I hope we’ll see more of from Microsoft.

Oh sure. Microsoft loves open source. If your open source company is willing to admit Microsoft owns Linux, acknowledge the legitimacy of its proprietary standards, and put “whatever Microsoft wants.”

What a goldmine my inbox was this morning. I also received the news that Microsoft’s Windows Competitive Strategy team is searching, via Linkedin, for “a strong team member to lead Microsoft’s global desktop competitive strategy as it relates to open source competitors.”

Microsoft is determined to be a leader of the open source movement. It will once again be a “platinum sponsor” at the Open Source Business Conference in San Francisco next month and its National Technology Officer for the U.S., Stuart McKee, will deliver a keynote.

There is power in authority. Microsoft's strategy against open source uses authority. It ties up institutions that are authoritative, that have power over professions, creating a benefit for the institution that ties its members to proprietary Microsoft tools....To Microsoft open source is not an end in itself. It is a marketing tool. It is a way to gain lock-in with important customer sets.
