See also the "Dissident" test in the DFSG FAQ. I'd question whether "you must send a mail, but sending anonymously and encrypted is OK" would make this type of thing pass the CD test, either. If I'm under threat of death if the mail is discovered, I'm not going to want to send it at all--I don't quite trust gpg and anonymizers with my life, and a free license shouldn't force me to. This is why I tend to lump the CD test and the DI test together; they usually have the same effect: no compulsory comunication. > * It removes the user's right to distribute private modifications (such > as writing a modified version of the software under a contract for a > particular organization). Not really--you just mail the author, saying "I'm distributing a modified version".

There's also generality--if I'm using ten code snippets with such licenses from different authors, I have to send ten such mails; if the kernel did this, I'd have to send hundreds. -- Glenn Maynard
