Engaging communities against Linux and OpenOffice.org

I like paradoxes. Paradoxes of all kinds always facinate me. They enforce you to think and often reveal deep understanding on how things work. You can read my analysis of the Paradox of the Cloud in an earlier post.
This is why I was amused to read Glyn Moody's blog post about a Microsoft's job description.
Microsoft wanted to recruit somebody to fill the “Linux and Open Office Compete Lead, US Subsidiary (CSI Lead)”. Glyn was concentrating on what CSI job description meant for OpenOffice.org. But, I want to stress here the paradox that is apparently inherent in how Microsoft treats the Open Source community.
According to Moody's blog post the job ad contains the following words: "The core mission of CSI is to win share against Linux and OpenOffice.org by designing and driving marketing programs, changing perceptions, engaging with Open Source communities and organizations, and drive internal readiness on how to compete with Commercial Linux and participate with Open Source Communities."
What caught my eye is the paradox of "win share against Linux and OpenOffice.org by ... engaging with Open Source communities and participate in Open Source Communities". Linux and OpenOffice.org are Open Source communities, among other things. So, how can Microsoft engage and participate with Open Source communities and act against them?
I think this paradox is not coincidental. Microsoft's engagement with Open Source communities is not aimed for the better of Open Source, but for the better of Microsoft against Open Source. It doesn't have to be like that, just look at the engagement of RedHat and IBM in Open Source communities and you can see that a good engagement is not against something but for something.
The only one that can solve this paradox is Micrsoft itself, and until that happens, Open Source communities should not trust Microsoft.
