OpenOffice.Org Now Under LGPLv3
I Don't Believe in Imaginary Property writes "Sun has moved OpenOffice.org to the LGPLv3 license. In his blog Sun's Simon Phipps cites worry over software patents as being one of their main reasons for this move: 'Upgrading to the LGPLv3 brings important new protections to the OpenOffice.org community, most notably through the new language concerning software patents. You may know that I am personally an opponent of software patents, and that Sun has already taken steps in this area with a patent non-assert covenant for ODF. But the most important protection for developers comes from creating mutual patent grants between developers. LGPLv3 does this.'"
Because it takes as payment the entire work of someone who relies on the supposedly "free" software.
The LGPL only requires such payment if changes are made directly to the LGPL'd work itself.
That's because Microsoft based their document on Sun's. I know that because the author of the Sun covenant is a colleague, because it was released at least a year before Microsoft copied it and because, after I pointed this out, Microsoft credited Sun for the original document.
I disagree, and I have explained why before on my blog. Sun's covenant is intended to empower open source developers, and Microsoft has altered the parts that make that happen. Most notably, Sun's covenant grants all patents, Microsoft's is limited to "necessary claims". That is a very major difference since it means open source developers cannot be sure they have actually been given cover by Microsoft's covenant whereas they can be certain they have by Sun's. It is deeply regerttable that Microsoft added essential claims language in this way. For those who don't follow links, I also find the conformance requirements and the patent peace asymmetry poor in Microsoft's document.
Indeed, and I am among them. However, your implication that the same applies to Sun's covenant is incorrect.
