I think that true crypt was issued a national security letter.
1) there is an audit performed on true crypt after thousands of dollars were fund raised to check its strength
2)it is verified to be a strong open source security measure and no backdoors/vulnerabilities were found, it got quite popular in technical news sites
3)shortly there after being verified as awesome the project shuts down and the first 3 letters of the first sentence on the reason for shut down webpage are N S A.
So after getting all this popularity and critical acclaime the developer decides to call it quits?
Its like, working in the shadows all this time. Instead of feeling the energy boost/euphroia from your new found popularity (after being told your programming is insecure crap so many times), you, fighting a one man war to keep the man from digging through your stuff, decide to close the project down??
THe excuse he gave is weak, i run a non networked computer with the russian version of alitum designer on it, it cost like 100$ to do. (complaining about windows library).
Anyone who thinks its not a NSL is like

personally I'd just delete the webpage and link a youtube to a certain clip from the movie "the pianist".
