I find it impossible to believe Lucasfilm doesn't know about it, though. Maybe someone at Disney would take notice, but my assumption (which is just that) has always been that they just don't consider it enough of a threat to their business to risk angering their most loving fans. I guess if the DeEd got so popular that thousands of people were downloading it, but even then, that would just prove there's a market for releasing the original film properly.

But that's me talking from a place of common sense, a concept which is in very short supply in the US these days.
