That's a worthy cause. Copyright extension is perfectly useless for people who create new stuff and only a means to securing the dominance of organizations that are increasingly made irrelevant by the radical changes in the media distribution landscape. We don't need our legislators spending time, energy and money on building perpetual streams of income for antiquated forms of content usage. Perhaps they'd be much better inspired to consider enforcing Creative Commons as the official copyright management system.
