"We are in a liminal period where copyright is sometimes enforced, and sometimes not. Social pressure and business inertia causes some people to play by the rules. Risk taking, greed, and ignorance causes other people to not do so. Where this ends up is anyone's guess, but it isn't likely to stay this way for long."

It's more nuanced than that - modern copyright is not doing what it was supposed to do (http://zacharyalberico.com/post/16427595132/no-infringement-...).
