Microsoft Tech Specs Prohibit GPL Implementations

The licence specifically prohibits any GPLed or (or LGPLed) program from implementing it, defining it as an 'IPR Impairing Licence'! Fortunately the CIFS community is about to release its own Technical Reference based on earlier MS documents and long experience in attempting to interoperate with the MS product." Microsoft's claim is completely ungrounded - nothing written by a third-party can take away Microsoft's intellectual property rights. But it makes a good (read: confusing to the general public) justification for preventing others from interoperating with their software.

Not just GPL by delta407 · 2002-04-05 03:56 · Score: 4, Troll

This is kinda creepy.

1.4 "IPR Impairing License" shall mean the GNU General Public License, the GNU Lesser/Library General Public License, and any license that requires in any instance that other software distributed with software subject to such license (a) be disclosed and distributed in source code form; (b) be licensed for purposes of making derivative works; or (c) be redistributable at no charge.

Microsoft seems to have just banned any open source or even free (as in beer) CIFS implementations.

Then, my question becomes: what about interpreted languages? Many languages don't have a compiled form... does the license prohibit those?
