"Forcing authors to lose rights" - NO! A common misconception. *Some* rights maybe, but only to guarantee the rights of the public!
This is the central question in all authorship legislature and morale: how to balance the rights of the public and the rights of an author?
Author should receive all attribution and credit, and certainly has the right to that. He also should have the right to forbid this attribution if parts of this information are used inappropriately (e.g. pasting a face into a pornographic image, or farting a sonnet); he should, however, be able to forbid the public of composing and publicizing the inappropriacies.
Public should receive the right to enjoy the work, spread it and re-use it, in the name of productivity in an information society. Out of pragmatic point of view, information is only useful when it's used, i.e., copied, spread and applied (or enjoyed).
Freedom of information (or freedom of speech, if you will) must go before the freedom of men to do what they please. The first is feasible, the latter is not.
