On the 26th June 2007, Eben Moglen gave a talk on "The Global Software Industry in Transformation: After GPLv3" hosted by the Scottish Society of Computers and Law, at the Edinburgh University School of Law. This was a highly interesting talk, and particularly topical, since the official release date for GPLv3 was just 3 days later, on Friday the 29th of June 2007.
I read the transcription on Groklaw, but there's also one on James Eaton-Lee's site (linked above) and one that's harder to read on the Internet Archive. There's also a video if you have the bandwidth.
Please take the opportunity to read it; Moglen's speech covers much more than merely the GPLv3 and the software industry, but also the changing world we live in.
