ファイル共有
In the case of file sharing networks, companies claim that peer-to-peer file sharing enables the violation of their copyrights. File sharing allows any file to be reproduced and redistributed indefinitely. Therefore, the reasoning is that if a copyrighted work is on a file sharing network, whoever uploaded or downloaded the file is liable for violating the copyright because they are reproducing the work without the authorization of the copyright holder or the law.
