Apart from one Tor developer who, without presenting any details, claims there was a "warrant canary" from Truecrypt almost 10 years ago, can you cite a single crypto expert who believes that this is the case? Or are you just saying about Truecrypt what you could say about virtually any other privacy-relevant software on the Internet at any time?

But there's a secret message in Latin. How much more proof could you ask for?

If that's the case (and it doesn't seem that unlikely to me), I think a thank you is in order.

Thanks buddy!
