Microsoft’s tactics against GNU/Linux have not changed much in two decades, they’re just framed differently, nowadays the attacks are masqueraded as friendship and proxies are used more than before. So as a fresh look at how these established tactics are used currently to attack Free Software, a guest poster at TechRights [techrights.org] has summarized them in a ten-chapter handbook, aptly named A Handbook for Destroying the Free Software Movement. The first two chapters cover what Microsoft is now doing through GitHub, licensing, Azure, Visual Studio, Vista10, and its other components foisted on developers. Other chapters cover manipulation of media coverage, OEM lock-in, use of attack proxies, and software patents. Most of all, these tactics have stayed true to the plans outlined over 20 years ago in the Halloween Documents.
It's written a bit tongue in cheek from Microsoft's perspective. Some material is drawn from Comes v Microsoft [groklaw.net] (aka The Iowa Case) and, as mentioned, the leaked internal memos known as the Halloween Documents [catb.org].
