GNU, GPL, Open Source The whole FAT licensing saga between Microsoft and TomTom just got a whole lot more complicated. Microsoft sued TomTom because the satnav maker had not licensed FAT from Microsoft, even though several others have. This left TomTom in a difficult position: not license it, and face legal penalties - license it, and violate the GPL. The second part, however, is up for debate now: the terms under which Microsoft licenses FAT may not violate the GPL at all. Near-instant update: On Slashdot, Bruce Perens and Jeremy Allison have explained that the FAT terms are still a GPL violation. Allison accidentally emailed the journalist who wrote this story with the wrong information.

i don't get how this in the slightest way has something todo with the gpl

when you follow the link in the article to the license-terms for fat you can read

To help licensees implement the FAT file system, Microsoft will provide certain reference source code and test specifications as part of the licensing package with both licenses.


nowhere does it say what implementation you must use, just that you have to guarantee compatiblity with the specification

tomtom could just license it, run the necessary tests, and be done with it
if the vfat implementation of linux is as good as is should be they won't even have to edit a single line of code

And they would get around the GPL's requirements WRT patent encumberment... how? MS has seen how to put TomTom, and anyone else who uses GPL'd vfat code between a rock and a hard place. They could sue the 4 authors of the vfat code in the Linux kernel:

Werner Almesberger
Gordon Chaffee
Wolfram Pienkoss
OGAWA Hirofumi

but they have chosen another strategy.
