Not quite, though. The page says "The development of TrueCrypt was ended in 5/2014 after Microsoft terminated support of Windows XP." We can infer that the two are connected, but it would be equally valid to say "The development of TrueCrypt was ended in 5/2014 after Snowden interviewed with NBC."

The reason I make this distinction is because continuing from a cautious/paranoid perspective, the DMS might not say "WARNING! Dead Man's Switch Activated! If you are reading this, I may have been compromised, and am no longer available to maintain TrueCrypt." It's possible that the landing page simply references a relatively innocuous event in the cyber security world to plausibly discontinue the software. The best evidence I have for this is the fact that TrueCrypt didn't shut down precisely when XP support was dropped. (In fact, according to http://www.microsoft.com/en-us/windows/enterprise/end-of-sup... official support ended in April, not May like the landing page states.)
