I see only issues abandoning copyright (for example it is the protection that makes Open Source Licenses work), but we should definitely discuss the length of it. The current trend of longer and longer periods of copyright protection can be questioned and I wonder if society would not benefit with a severely cut copyright period. Berne convention and other international treaties makes it hard to change below Life + 50 years, but I see no reason all the right incentives for individuals and companies would be there if you cut it to just 20-30 years after publication. The benefits of new derivative works, access and sharing knowledge and other areas would be great for society as a whole.

The moral right of claiming ownership to a work should still be protected forever.
