It just doesn't make sense that the TC devs would recommend BitLocker and put up that hastily posted instruction on how to use bitlocker. No matter which way you cut it, it just doesn't make sense at all.
NSA can't kill TrueCrypt because the source code is already out there and there is no taking it back. I think what they can and did do is prevent TrueCrypt from becoming adopted in mass, which after Snowden incident and after the audit turned up no backdoors, was very likely going to happen. Most likely, NSA would likely not allow TrueCrypt developers to keep developing and had they released a UEFI/GPT version, then TC would become widely used going forward. So it was imperative for NSA to kill off TrueCrypt before that happened, and to leave an ever tiny user base that purposefully goes out of their way to use legacy BIOS for FDE.
The goals was prevent TC from being adopted in masse, which likely would have happened given the convergence of 1) Snowden's disclosures and the public uproar with regards to privacy 2) a future version of TrueCrypt fully supporting UEFI/GPT/Windows8/9/etc 3) an audit that cleared the suspicions and gave TrueCrypt a clean bill of health and publicity.
