While I agree with you in spirit in practice I find copy right laws oppressive. I can see providing protection from copying for 8, 10, 12 even 20 years but protection FOREVER is a bit much. The copyright laws should be reformed to provide a reasonable amount of protection. At some point the works should be in the public domain. Just as patents expire so should copyrights.
Bring back the original term of copyright (14 years, 28 with application for extension) and I am absolutely ok with aggressive enforcement.
But if I'm on a jury if the issue is pirating 40 or 50 year old materials, I vote to nullify every time.
