T-Rex: Copyright is intended to prevent others from ripping off your creations! It used to extend 28 years after you created something, giving you a chance to profit while ensuring good ideas would eventually enter the public domain.
T-Rex: However, lately it's gotten pretty ridiculous!
T-Rex: Copyright extensions have pushed this protection up to the length of your life plus 70 years and beyond - basically, whenever Mickey Mouse is due to enter the public domain, copyright law is extended. It's unfair, and it restricts creativity!
Utahraptor: How does it restrict creativity?
T-Rex: Well!
T-Rex: With these insanely long copyright laws, there is no new public domain, and our modern culture is owned and put in private hands! It ensures you can't build on anything that's been created in the past 70 years.
Utahraptor: Wow, you really seem to care about copyright laws!
T-Rex: I just think we're approaching a state of perpetual copyright, and that this could interfere with my bhangra remixes of pop songs.
T-Rex: I mean my non-bhangra remixes, of course!
T-Rex: THEY'RE GOOD
