Lessig has just written about the experience of seeing himself portrayed on TV, and he generally seems happy: http://www.lessig.org/blog/archives/002421.shtml

I haven’t seen the video, but I’m glad that the Lessig didn’t trash the RIAA (too obvious), and besides, he is on record as supporting copyright as it was intended, as being protection of creative works for a limited time, so expecting him to disparage copyright law ignores his nuanced argument both for it and the need for alternatives that co-exist with it. Also, the word “just” is misplaced here: a former Soviet state getting a reliable constitutional document (and, more importantly, as Lessig writes, a culture that recognizes the rule of law) is–or would be–a pretty substantial achievement.
