We can argue all we want about whether copyright is good or not, but that is the wrong question. The right question is if (enforced) copyright is compatible with the existence of a free internet.

IMHO, it is not. Current copyright law means restrictions on the copy of data. A free internet means freedom to interchange data.

So either we lose the free net, or we push for a deep reform of IP laws, something like that the law should only restrict for-profit infringement.
