Of course you are. That's a fun thought experiment. Details of licensure, burned out developers, and Truecrypt's modern place among all the other encrypted storage schemes are much more boring than the cloak and dagger fiction of a Truecrypt warrant canary.
Since the developer(s) is/are anonymous - why would they need any elaborate way of telling people this? They could just state that they consider the code compromised and advise not to use it anymore.
