Human Knowledge was develeped socially, its fruit should be shared socially. The commercial use of other people’s work is unethical and it’s basically what every copyright holder company do, with or without the permission of the author. To lock human knowledge behind copyright is more than simply wrong, it’s elitism. Thanks to piracy, several books that aren’t published anymore, several games and several movies were able to remain. Doctor Who, for example, have tons of episodes that only exists nowadays because someone recorded them.
