I need to check if "Sausage Party" is indeed available there and if there have been notices about it. The Internet Archive has faced DMCA takedown requests, so maybe "Sausage Party" has been removed due to that. Also, mention how the Archive defends its practices through the concept of fair use, but that's often challenged in court. Users might access it thinking it's legal, but they could be violating laws.
