If you shoot someone, take all his money, then build a business with it, you're still a murderer. (Just now you're a rich murderer.)
Right? There were even competitors back then. People all but forgot the Looney Tunes.
i.e. enforce egregious IP violations while criminalizing trolls.
The long timelines stifle new creative works by keeping other, especially smaller, outfits having to make sure they don't accidentally run afoul of another copyright from decades ago. This needs capital to either be proactive in searching or to defend a suit that's brought.
Here's a recent article about the battle between the copyright holders of Let's Get It On and Ed Sheeran for Thinking Out Loud. Those two songs are separated by around 40 years. https://www.theguardian.com/music/2023/may/07/ed-sheeran-cop...
Copyright has been the most powerful tool in any media company's toolbox when it comes to consolidating power and IP and rolling into a larger and larger ball of what we call culture.
So that is still something possible to do in roughly 20 years.
IP law reasonably does. See: https://trademarks.justia.com/852/28/the-little-mermaid-8522...
You don't think it's them being allowed to buy Marvel, Pixar, Lucasfilm? Is creativity ruined because I can't make a Mickey Mouse cartoon or t-shirt? Does the world need Luke Skywalker coming from any individual studio?
People are free to make the Little Mermaid, Beauty and the Beast, Hunchback of Notre Dame, Aladdin, etc. and there's nothing out there that stops them.
I've got no love for giant corporations but I see it a lot less about copyright than massive corporation gobbling up more corporations. There's no shortage of creativity out there if you look for it.
