This has nothing to do with DMCA, it is plain old good trademark law and the idiotic "use it or lose" clause in it. That clause is long overdue for clarification and relaxation
Only somebody who's never discovered the joys of safe harbour in the DMCA would say something so silly.
Actually take away the safe harbour stuff and the DMCA would be a reasonably functional piece of copyright legislation. It'd still excessively favour copyright holders but at the same time at least people could make it work.
Making bullshit copyright claims should implicitly be viewed by the legal system as perjury and result in people being disbarred when they do it and then they might actually look at the shit they're sending out. Yes I am suggesting lawyers should lose their livelihoods for a first offence, then maybe it'd restore faith in the system and practitioners.
