The GPLv3 in Plain English – The Parts Microsoft Worries About

Awhile back I read the small print about Microsoft’s Moonlight software distribution. It specifically mentions the stuff they don’t like about the GPLv3. Interesting. Let’s see what they are worried about.

“Any other license or contract that includes terms similar to the terms in paragraphs 6 or 7 of Section 11 of the GNU General Public License version 3.

How bad could it be? Now, I’m not a lawyer. But when I read the sections they don’t like … it’s littered with phrases like “propagate by procuring conveyance” which sounds something like this in my head: “blabbity unicorns blah and cucumbers might take blah over dick tracy the world hurmph.” What exactly does Paragraphs 6 or 7 of Section 11 of the GPLv3 say? Here’s the block of unreadable text in its’ entirety:

If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it.

A patent license is “discriminatory” if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License. You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a) in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March 2007.

Whiskey Tango Foxtrot Batman! What the fsck does that say? Here’s my plain English translation:

If you (or one of your partners) provide software licensed under GPLv3, and agree not to sue anyone — the agreement not to sue (and the use of patents that are in the software) will apply to all future recipients of that software.

Any patent agreement which attempts to nullify any rights given to you or others in the GPLv3 is invalid. This includes paying a partner distribute the software for you and agreeing not to sue them.

Did the meaning change significantly? I’d say not very much. Is the spirit intact? I strongly believe so. If you violate any part of my “plain english” version, you almost certainly violate the original document. Someone is bound to argue that I’m simplifying this too much — you’re absolutely right. This is the point.

    Read the EULA from Microsoft and tell me you don’t feel the heavy hand of tyrrany slamming your head through your neck into your chest cavity. I’ll take the GPL v3 thanks.

    Legalize wasn’t intended for they layman to understand. It appears to be english but is not. Use real English and watch the laywers rape you of all your wealth and freedom.

    Richard Stallman must have had a big head spliff in his jaw as he wrote that :D If you can speak a second language then you might have a chance of understanding
    it. if I understand what is there then it’s like: if one licences a part of a patend sortware under the GPLv3 and that software got modified under the licence then then the GPLv3 is automatically a co-owner of that patent.
    That is damn cool!
    But it could also means that Windows is a part of the Linux code ;)

    Um moonlight is not microsofts’ software. From the small print. “software plug-in developed by or on behalf of Novell”.

    I must disagree with your post, I just don’t believe all the “truths” are clear. I do have fun reading it, so keep at it!
