The inability of copyright to regulate cultural activity isn’t anything new. It’s probably true that this inability reduces the profitability of some entities in the entertainment industry’s supply chain, just as it increases others’. But that’s just a question of profit maximisation, not survival.
The problem is that the entertainment companies treated the increased ease of copying in the age of the internet as a signal that copyright should be expanded to cover more people and more activities, far outside of the entertainment industry. What they should have done is picked a new proxy for “this is an industrial activity within copyright’s scope” and soldiered on regulating themselves, without trying to regulate the whole world at the same time.
It’s time to stop declaring copyright dead because we aren’t willing to let it be the ultimate regulator of everything we do with a computer.
