They don't owe anyone on HN or anywhere else any kind of "ownership of statements" or explanation. The published some source code. They got sick of it. They've moved on. It's over.
I understand the urge people have to synthesize a soap opera narrative out of things on message boards --- that's fun, after all, and the alternative is boring. But that's all the conversation about the TC project abandonment really is: a synthesized soap opera.
The circumstances were fishy - in a way that says don't trust the software to anyone that has anything to hide.
Using TrueCrypt is not secure as it may contain unfixed security issues.
I don't think the developers owe anyone anything, in terms of supporting this project or even justifying their decision not to support it. But they did make this claim, which they didn't need to, which casts the entire project in doubt. You're saying they are refusing to elaborate on this claim? Or has no-one asked them to? Because I think this thread is evidence enough that plenty of people want to know.However, I still use TrueCrypt because I'm familiar with it, don't believe it has been compromised, and I trust a random pickpocket will be unable to break it.
(Also to clarify, when I said 'take ownership of this statement' I was referring to the earlier conjecture that the message was written by people other than the original developers.)
