Looking at the article again I realize the headline here may be incorrect. It is not proven that Le Roux wrote TrueCrypt, but he definitely built the foundation for it.

> Hafner and his SecurStar colleagues suspected that Le Roux was part of the TrueCrypt collective but couldn’t prove it. Indeed, even today the question of who launched the software remains unanswered. “The origin of TrueCrypt has always been very mysterious,” says Matthew Green, a computer-science professor at the Johns Hopkins Information Security Institute and an expert on TrueCrypt who led a security audit of the software in 2014. “It was written by anonymous folks; it could have been Paul Le Roux writing under an assumed name, or it could have been someone completely different.”

Interesting read, regardless.
