"The first phase of the TrueCrypt audit found no serious problems with the Windows build of TrueCrypt."

There is a theory that the TrueCrypt developers were approached by a government body and forced to weaken the security of TrueCrypt, and also forced not to tell anyone about it.
And so this would be their way of them telling us about it without actually telling us.
The fact that they recommend we switch to a closed-source Microsoft solution is just laughable. Their advice for Linux users is "search for some other package".
Something fishy is definitely going on.
