I have a situation here. Some (Iranian) people have copied my LGPL code without even attribution, and they deny it. The whole story is dirty, but is basically that they thought Open Source means public domain, and have even submitted my code to the Iranian government as a part of a contract, assigning "their" copyright to the governmental agency in the meantime! They have probably understood the issue since (I have explained it to them in person), but can't do anything about it, since them accepting that they copied my work would mean that they should either return the governmental money (which was at least about USD 17000), or replace my code (which they are incompetent to do).
I am following it up with the governmental agency (which is very probably unaware of the issue), of course, and am thinking about courts and all. (Any recommendation is welcome.)
The infringing code is even in the evolution-hackers archive. I posted a message there asking for the message to be removed from the archives: http://lists.ximian.com/archives/public/evolution-hackers/2005-March/005261.html
Is it impolite/bad/evil/something to ask for unlicensed copyrighted work to be removed from a mailing list's archives?
