Truecrypt is a high quality open source project that has been updated diligently for many years. For its developers to abandon it in such an immature fashion was highly bizarre. The possibility that they were sending a deliberate signal with this act was one of my first thoughts. I don't consider the article posted here to be plausible evidence, but it certainly gives voice to my suspicions.
Truecrypt's developers, if they indeed live in the U.S., may have done as much as they can do. It is now up to the audit team to evaluate truecrypt as thoroughly as possible and, should truecrypt prove sound, it will be up to international teams to pick up the torch. It's certainly possible that a completely different country is cracking down on truecrypt's developers, but this action fits the NSA's modus operandi perfectly.
