When things are made artificially scarce, they get hacked. When movies are DRMed, the DRM gets stripped. When there is an attempt to block or shape BitTorrent, BitTorrent responds in kind. One could argue that piracy in films is largely caused by the stupidity of having different release windows for films in different countries. A separation in time that is no longer necessary and often insulting. At least now we don’t have DRM in music any more.
