I don't dispute that sharing has been made deliberately more difficult in the digital media age, and by parties interested in maintaining -- or at least prolonging -- that difficulty. I'm not fully convinced, however, that this difficulty has actually changed consumer notions of what is, and is not, ethically sharable. I haven't seen enough data on consumer perceptions or beliefs; all the data presented so far can just as easily be explained by the difficulty of sharing in and of itself. (Note that I'm not saying perception changes won't ever happen; I'm merely saying that I don't know if they've actually happened just yet).

For the record, I am pro-sharing, and I believe that IP holders and media companies who would do their darndest to prevent sharing are incredibly short-sighted. They wring their hands about the need for (evidently magical) "viral marketing" of their material, while at the same time inherently limiting the ability of their consumers to do a lot of the peer-to-peer marketing that they used to do.
