If I have got the facts correct, most authors derive any income from their works in the first 3.5 years. Organisations like Disney et al are not authors but are gatekeepers and hence any benefit that they derive from copyright should be eliminated. Hence, copyright should be a maximum of 7 years, consisting of 3.5 years initial and a explicitly asked for 3.5 years extension. Go back to the officially request copyright and if not done it is automatically public domain. This would be the most beneficial to authors and the public as we really need to discount any benefit to the gatekeepers. There are jurisdictions where an author cannot legally commit his/her work into the public domain as the law forces protections they do not want on to them.
