Slashdot interviewed Ibiblio Director Paul Jones.

DRM is the general term for the groups of solutions to the need for creators to be compensated for their work while allowing their audience to easily access those works. Or at least that would be ideally what DRM should do.
When DRM goes wrong, it tramples on the rights of the citizens to have access to information that they have legally purchased, want to criticize, parody, legally reuse or share.
When DRM goes wrong, it creates barriers to innovation and creativity. It biases access and reproduction of information to only certain technologies.
When DRM goes wrong, it creates and perpetrates closed markets and monopolies.
When DRM goes wrong, everyone suffers. It takes us back to the Stationers Guild, a response to the printing press. “The Stationers Guild obtained monopoly rights in the printing and probably distribution of all books, a monopoly codified by the Tudors in a licensing system aimed at censoring religious dissent” which lasted until the early 1700s.
When DRM goes wrong, it is called Palladium.
The good news is that Palladium is vaporware – so far.
