A "puppet strategy" and a "proxy strategy" are closely related and the terms are almost interchangeable. We have already learned how Microsoft used Novell and others to empower the OOXML push.
A few weeks ago, Microsoft used Citrix as a proxy in its plot to steal XenSource from the Linux community and then subvert Xen's roadmap. It's a nice little strategy and Microsoft deserves credit for mastering the art of buying out its competition without getting the FTC's attention. Microsoft acquires proxies and then uses them to suit its own agenda and pursuit goals. Miguel de Icaza is probably the leader of the proxy element inside Novell, but that's not really the story which deserves attention at this moment.
It appears that the standard operating procedure for Microsoft will be to send open sourced partners into the GPLv3 car park.
