For a while the Microsoft folks have been feigning attempts at making peace with free/libre software advocates and even wooing developers.

- Invest in WINE. Make WINE so robust that free/libre advocates start buying Windows software.
- Publish full specifications for all Microsoft file formats. Word, Excel, Visio, et.al.
- Compete on the merits of software design rather than file format vendor lock-in.
