This software is a continuation of the now abandoned project TrueCrypt, a popular disk encryption application. All the new code is released under the terms of a free software license. On the other hand, the code inherited from the old TrueCrypt is still licensed under the terms of the custom TrueCrypt License version 3.0 which is not free software.

I found it in a lot of files:

Since the code inherited from the old TrueCrypt is still licensed under TrueCrypt License, it should go to the blacklist, thanks for the report!
