if you have heard him several times you can possibly tell others whether it is worth listening to him or not. There are several people on the list who have not heard him, some of them may want to see the person and listen from the horses mouth even if they have seen the video.
I understand what you said. People would like to hear from the iCON who has done such a big sacrifice of leaving AI labs of MIT to give the world free software which is free speech and free bear. He had the revenue model of selling the code he wrote on magnetic tapes and then with the advent of Internet and other accessories it failed.
Lot of people in IIT should be contributing to free software or to GPLed code in more than one sense.
I guess I have not seen something like that I come out of IIT. While the utility wget was written by an IITian.

What do you recommend to the people who have already heard the talk and taken conclusions from it.
