Here's why. Someone, Moglen says, is bound to turn a voucher it got from Microsoft in after GPLv3 goes into effect and GPLv3 code is being distributed, and at that moment Microsoft comes under its terms. And that should mean the end of Microsoft's ability to successfully sue anybody over its alleged patents allegedly in Linux, or to phrase it more exactly, it provides a probable defense to all Linux users and vendors, not just Novell's paying customers, if Microsoft does sue.
