It’s true that the TrueCrypt developers retired and said that commercial packages like BitLocker were finally good enough and available enough that they didn’t feel compelled to maintain TrueCrypt. I remember that. I think it’s plausible that Microsoft has (or has provided to someone) back-door access to BitLocker, but I don’t remember any hint that the TrueCrypt developers had been coerced; have you got something you can link to?
There’s an open-source successor to TrueCrypt called VeraCrypt. For that matter, as far as I know, one can still download the last version of TrueCrypt. It hasn’t been disappeared.
