From the Common Enemies dept.:
The two organizations haven't been what you'd call snuggle-buddies, but they're certainly adamant about certain aspects of software enough to agree and collectively petition a legal group for redress of a document. In a somewhat surprising move, Microsoft and the Linux Foundation have joined forces in writing and signing a letter to the American Law Institute asking for the group to hold off on submitting a document entitled "Principles of the Law of Software Contracts" for adjustments.

...The section of the principles that bites Microsoft's and the Linux Foundation's bottoms is a part concerning warranties and defects in software. According to a ChannelWeb article, "one warranty would make software developers liable for infringing on patents and copyrights, while the other would make contributors to open-source software liable for material defects in the software. The law currently allows contributors and licensors of open source to avoid liability by offering their wares on an 'as-is' basis."
