Microsoft not only violated the GPL before releasing some kernel hooks for Microsoft's proprietary software [1, 2, 3, 4, 5, 6, 7, 8] (Microsoft sent out Ramji to spin it, but he's quitting the company now); it is also showing total lack of interest, if not just the expected indifference. Their semi-ally from Novell, Greg Kroah-Hartman, is now complaining publicly and Microsoft blogs are seeing this.
Greg Kroah-Hartman, a Novell fellow with SuSE Labs and Linux Driver Project lead, posted on September 9 a status update on the drivers being assembled for inclusion in the Linux 2.6.32 kernel, Kroah-Hartman had some harsh words about Microsoft’s participation since its original announcement of its GPL plans in late July.
Microsoft's developers were missing in action after the company donated GPL-licensed drivers to the Linux kernel community in July, leaving significant work to the Linux community, according to Linux driver project lead and Novell fellow Greg Kroah-Hartman.
