WarPengi writes "This report has been out for a while but it gives some great info on the GPL and FOSS. The following caught my eye. Here we have evidence that MS has used that "communist, viral" GPL in their products.
"even GPL with its strong protection of transitive user rights provides a number of mechanisms to allow such mixing. Microsoft provides a good example of an innovative use of one such mixing strategy in their Windows Services for Unix (SFU)6 product. This product uses proprietary software to build an initial bridge between Windows and UNIX operating systems, and then adds in GPL tools and utilities to extend greatly its overall emulation of UNIX. Users benefit from the extended functionality provided by the GPL components, while Microsoft benefits by avoiding the cost and time of re-developing the tools as proprietary software.""
