I'm not sure I know of a professional cryptography engineer who believes that what happened with Truecrypt is anything more than what that developer said. Can you cite one?
TrueCrypt's developers chose not to graciously turn their beloved creation over to a wider Internet development community, but rather, ... to attempt to kill it off by creating a dramatically neutered 7.2 version ... - Steve Gibson
I have no idea what's going on with TrueCrypt, Speculations include a massive hack of the TrueCrypt developers, some Lavabit-like forced shutdown, and an internal power struggle within TrueCrypt. I suppose we'll have to wait and see what develops. - Bruce Schneier.
Steve Gibson isn't a cryptographer, and your quote doesn't respond to my question.
Bruce Schneier I'll have to accept as a totally valid rebuttal to my implied point. This is something that really irritates me about Schneier, for what it's worth. He's also behind a meme that elliptic curve cryptography is less safe than RSA, when the reality is almost the opposite.
