Here’s a better approach: circumventing copy protection schemes shouldn’t be against the law in the first place. DRM schemes harm legitimate users more than they deter piracy. Indeed, as the phone unlocking example illustrates, many uses of DRM have nothing to do with copyright infringement in the first place. Rather, they’re a convenient legal pretext for limiting competition and locking consumers into proprietary products. We shouldn’t be using copyright law as a backdoor means to give such anti-competitive practices the force of law.
