As a great opponent of any form of IP, I have been following the event of Disney's Steamboat Willie entering the public domain with great amusement. The incidents where creators have been falsely demonetized on youtube for rightfully using this film is further underpinned by Disney's decades-long shameless practices. The linked article sums it up quite well I think.
We have lost much having to wait for meds patents or other useful technologies.
And even in the entertainment industry we have probably lost so many masterpieces that could have been inspired by copyrighted material. Of course, that we will never know.
Patent. Not copyright. What things of scientific value have been blocked or discovered via copyright law. That sounds like nonsense. This is all entertainment and I can't think of a single case where copyright has affected cultural change.
Both are based on the absurd concept of intellectual property. They are the same cancerous thing that is crippling technological and cultural advancement.
Edit: Seeing your comment history in the piracy community, I don't understand why you bother commenting. It's pretty clear that you're a corpo buttlicker. I'm sure there are communities where youd be better received.
If I spend an entire article talking about ways that school dress codes fall afoul of cultural values because Scot sometimes wear kilts, am I not talking about dress codes?
Just because you can't extrapolate doesn't mean the rest of us shouldn't.
