On Lessig vs Keen (required 6)

After reading all of Lessig's points against Keen, I really feel as though Keen is a sore spot for Lessig, as though he has some personal vendetta against Keen. Some of his counterpoints against Keen's arguements are good; for instance the google counterpoint. I agree with Lessig that as efficiency is increased that creates increased value, thus validating google as an enterprise in aggregating websites just as phonebooks aggregate addresses and phone numbers. I say that it seems as though Lessig has a personal vendetta against Keen because of his comments about keen being sloppy. Through out his wiki site and his book critique Lessig calls Keen sloppy and pretty much an exaggerator of the truth; the problem I have with this statement against Keen is that Lessig fails to provide any data that shows Keen is actually incorrect. Taken from the wiki site: "Over the last 10 years, the listening hours of eighteen to twenty-four year olds have dropped 21 percent. (p123) Sloppy: what percentage of the 21% is because of "piracy"? The people who wrote the site are questioning the accuracy of the quote, but it's clear that they were never interested in actually proving Keen wrong, otherwise they would have found the hard evidence instead of just trying to call him out on using hyperbole for dramatic effect. I do not exactly agree with Keen that the amateur is a cult that needs ending, but at least his points are backed by data and are not just angry remarks from an upset writer.
