I am not against the idea of copyright. I'm not even against the idea of using technological means to enforce copyright, as long as they do so in an ethical manner. By this, I mean that the rights of legitimate users must never be infringed in any way, erring on the side of presuming innocence if need be, and that the terms of the copyright must be respected.
I have yet to see any form of modern DRM which does this. I've seen some software antipiracy schemes which do, but these have fallen out of favor in recent years. Truly, it is a sad situation when the creators have forgotten that the users have rights too.
