That is really a problem with trademarking, or plagiarism, this at heart is basically a lie, you are saying that you invented a product, or your product to something that is not.
This is the only intellectual property I agree with, people should have the right to protect their reputation. If you wish to make a cheap rip off go right ahead as long as you make it clear that it is a cheap rip off.
I believe Copyright, and Patents do more harm than good, their maybe a need for them but they should be very limited, and as technological improvements speed there lifetime should decrease not increase. I have not seen any actual study (that goes beyond, look loads of people are downloading, so we must be losing money, so we must be creating less) that shows patents or copyright actually promote creativity and innovation. for patents https://www.youtube.com/watch?... also doesn't. (I am not saying that this video shows having patents leads to more innovation just it shows there is no proof to the contrary.)
There are psychological studies that show paying people more actually reduces their creativity.
My opinion is that all works of art, and innovations are based on other works of art and innovations, limiting peoples ability to create based on the work of others, severely limits, the ability of society to create and innovate. With creation of the internet we have made a tool that we can now easily share ideas with anyone in the world, it has unlocked the potential for huge advances in both art and science. Instead of embracing it the people with power, want to limit is so that they can maintain their wealth and power, don't share that's bad.
For example, imagine if we all had access to the 3D models that all these animated movies have already created, how may people would go out and produce their own stories based on them? Would it not mean we have a much more movies produced?
