Ok, but the source code was published, everybody could see it. Of course, according to the definition, you need to actually be able, legally, to modify the SW - and from what I gather from this discussion, TrueCrypt creators had copyright on the source code? (this I did not know) How do you call SW with public source-code that maintains copyright? Apparently it isn't "open source", but what is it?
