Are you willing to put you interpretation of copyright to the test? Why don't you write a modern retelling of Cinderella based on Disney's version and see how far you get. Next try a remix between Cinderella, Harry Potter, and the leaked Windows source code and see what happens.
With a quick search I found 37 different film versions of Cinderella, I did not look at them individually to confirm, but it would be safe to say Disney did not create 37 versions of Cinderella. So a serious derivative work can be made that does not violate any Disney copyright, but I can certainly say I could create a zombie themed Cinderella that would fall under satire and not constitute a infringement.
I should also note that I am an attorney, and have handled both trademark and copyright infringement cases (for plaintiffs and defendants). That is in addition to successfully registering both and in some cases over objections of the examining USPTO attorney or third parties.
Edit: I don't know why I am being down voted but in the instance it sounds like I am saying I must be right bc I'm an attorney, I am the first to acknowledge disagreement between practitioners, jurisdictions, and Judge's/justices. For what its worth I noted it as a sign of good faith that I am not blowing smoke of my interpretation of copyright law
Perhaps Cinderella was a poor example due to its origins as a folk tale. Let's substitute Mickey Mouse for Cinderella in my example. Would I be able to write, publish, and profit from my own non-satirical Mickey Mouse stories if I clearly labeled them as not originating from Disney? What about 250 years from now?
I think part of the disconnect between your opinion of copyright law and some of the other commenters here is caused by the lawyer/hacker dichotomy. Hackers tend to view any involvement of the courts as a failure. For most non-wealthy people and most small businesses, the threat alone of legal action has a chilling effect.
An argument I make against long copyrights, especially for famous works, is that these stories and characters become woven into our popular culture. At some point, the public deserve to own their own culture, not megalithic corporations. Cinderella is the story it is because of the additions of different storytellers over time, like the godmother and glass slippers added in Perrault's Cendrillon.
>Perhaps Cinderella was a poor example due to its origins as a folk tale.
I used Cinderella specifically, bc my understanding is the folk tale was very unlike (violent, gory, ect...) the Disney version tailored for children.
In general satire is a much easier and obvious legal analysis as well. Say for example South Park's episodes with Mickey (although more of a Trademark issue than copyright), more on point with copyright is South Park's Star Wars episodes. However, to answer your question, is it possible to make a non-satirical Mickey story that does not violate Disney Trademarks? The answer is yes, but admittedly much more difficult and likely to infringe than a satirical story.
>Hackers tend to view any involvement of the courts as a failure.
As a lawyer, I see lawsuits as a cost of doing business and inevitable for any successful enterprise. I would encourage all hackers, especially, to view lawsuits in the same light (e.g. I am not successful until I get sued). I say this because hackers particularly set out to disrupt established industries, take Uber or AirBnB as good examples, but even YC itself has been sued, that is not a failure that is the cost of success.
> At some point, the public deserve to own their own culture, not megalithic corporations.
This is simply where we disagree, I am not saying you are wrong by any means, because I do not think their is a right answer, your point is sincere and well reasoned. My counter, is that the free market decides. Moreover, if Mickey is not going to win in the market place because society wants to take the character and run with it open source style, well then Mickey will lose in favor of another cartoon Mouse created by an pro open source artist, but I would say the reason Mickey became a cultural icon is because of the tight control of the story and character vis-a-vis Disney ownership/investment. In contrast and in support of your position Japan has a thriving culture based open source character, where even iconic corporate mascots are adopted by the public and the public creates their own stories, comics, commercial products, virtual concerts, ect...
