Are Cuckoo Eggs legal?
No. However, 1) Cuckoo Eggs are meant to deter piracy and 2) Cuckoo Eggs only use a short sample of the copyrighted work. Because of this, Cuckoo Eggs are more likely to fall under the terms of fair use than the trading of MP3s containing full copyrighted works. Therefore, while Cuckoo Eggs and MP3s of copyrighted works are both illegal, the trading of Cuckoo Eggs is more defensible than the trading of MP3s of copyrighted works.
