I’m not sure where I stand on this, but is it possible that some people have been convinced that copyright is a moral evil by propaganda? I pause when I hear this line of argument, “I’m a free thinker and I have objective truth. Others are weak minded victims of propaganda.”
Of course. There's all kinds of propaganda (and depending on where you stand, some propaganda is good and other propaganda is bad), and not one person is immune. But for the sake of this discussion, there are some extra factors to consider:
* Those promoting copyright expansion or the status quo have significant amounts of money; those criticizing it mostly do not (counting groups with real principles, anyway)
* It is suspicious for people who have no personal interest in extended copyright to excessively favor it.
