To be fair to "I Can Haz Cheezeburger", which admittedly is hard to do on forum like this, it brings entertainment to millions of all ages and hurts no one. Where are the negative side effects in that?
On the other hand, industries that rely on shipping an easily duplicable product with high up-front costs for development are likely to benefit from strong copyright enforcement. They are not on this list, in spite of being arguably more innovative.
Neither result is surprising, but saying "Entrepreneurs" and "innovators" are generally in support of less copyright legislation is disingenuous.
Where did that claim come from? What are you referring to?
