The Okular application says specifically, "copy forbidden by DRM".

My god it's good to be involved with the gang at LWN!
Made my day. Nothin like a regular dose of rationality. With class.
And Jon - excellent article! Clearly a timely raising of these issues.

DRM generally uses encryption, with the distinguishing feature of having the decryption key widely
known to all viewer software/hardware in the world. By thus controlling access to the encrypted
data by requiring use of the special software with the decryption key, the content creators prevent
users from accessing the content in objectionable ways. (or so they'd like to think).
This is exactly what the copy-prohibit flag in PDF is doing, except that the default decryption key is
actually documented in the PDF format documentation! That part is a little unusual for DRM, and I
suppose might make ignoring this flag not trigger the anti-DRM-bypass laws.

Circumvention is a valid possibility. AFAIK it is not illegal in the EU or elsewhere, so it can only be a problem in the US.

Plus, a quick read of the Directive 2001/29/EC seems to specifically prohibit circumvention of technical copyright restrictions. In Article 6, Section 1: "Member States shall provide adequate legal protection against the circumvention of any effective technological measures, which the person concerned carries out in the knowledge, or with reasonable grounds to know, that he or she is pursuing that objective."
