> It's self-serving hypocrisy when programmers argue for a very strict reading of copyright for their own works (source code) while at the same time arguing for unbounded sharing of other people's works (books and papers).

Yes, if those were the only two things being discussed, it would be.

But almost all of these people think a certain amount of copyright for songs and movies is good too. And I bet a vast majority of them support copyright for books too, or at least most books.
