I've decided to move this to its own thread, so it doesn't de-rail the other topics. Also moved all replies to this here, and deleted the OP copies.
As for this issue, I'm more concerned about possible NSA/*** infiltrators hiding in the dev team, rather than someone who doesn't hide his employment location. As stated earlier, Tor was created by US Navy, and from what we've seen in the Snowden leaks, it is a big pain for NSA to break.
Besides, the CS development process requires multiple people to audit the code before its added into the master branch, so if Jason would try to insert some sort of backdoor, it wouldn't just pass unnoticed(hopefully). Even if it did, at that point, we're reaching the point where it's impossible to prevent it.
One can never be 100% certain that a program doesn't have backdoors, or that the developers aren't working for the NSA/***. No one knows really who the TC devs are, but apparently millions use TC. Here, the people that audit the code before it's added to the program have given out their full name and everything, and evidently don't try to hide who they're working for (at least Jason doesn't). For me, this system is as trustworthy as one truly can get. Anyone who has a better system in mind is encouraged to suggest it.
