My view has consistently been that the U.S. Congress and others in the pay of major studios ,extended the length of copyright protection in excess of the original intents and well in excess of custom or logic.
The U.S. laws used to recognize the right of an individual to copy many inventions,etc. as long as only one copy was made for the person's own private,non-commercial use. use,none sold or even given away.Here is where computer piracy in the workplace and at club swaps violates even the long-accepted previous understanding.Copyright and patent protection also depended on the inventor or holder pursuing action against persons or companies making unlicensed products.
Warning!!!
Long post follows ,but I couldn't think how to cover the points shorter.
I still believe 14 or so years is long enough for a person to profit from exclusitivity,and then ideas should become public domain.However that is not the current law.
Personally I think if a person or company no longer makes the product available ,it should automatically become public domain.
I have electronic hardware for which the company exists but cannot provide repair or operation info,yet current law says no one can sell or copy .
Piracy in the form of copying products currently available for purchase surely hurts companies and the people who work for them;but copying products that are abandoned,while illegal,seems to me not so big a deal morally.
I would draw a parallel with items discarded into the trash by the previous owner in that if someone else can make use of those items that is not otherwise criminal in itself,then it is no wrong.
Traditional public or private libraries lending of material meant that only one person could use the item at any given time,so one copy of a book might be read by a hundred people in a few years,only a few of which might have bought the book .But if the library had made copies of that one book so that all users got a permanent copy free,then that would have meant no one else need purchase a copy.
IF computer club libraries had been able to function on that model,more software would have been purchased.Without all software being absolutely locked down into requiring the master disk present in a drive or other physical key present,software copying is common.Some business software today still requires secure keys in USB or port "dongle" form( of course a big chunk of program code is devoted to key or licenses verification and itself hidden ).I wonder how many lines of Windows code is used to monitor the license status?
