Personally, I think Binney has a difficult time speaking and, if he had written out his response, would have chosen a different word than "traitor," just based on the way he stuttered and struggled to complete that sentence.
I think you're right, and I think grey-area's quote (https://news.ycombinator.com/item?id=5902353) is probably more indicative of Binney's view. But his tentative way of speaking is for me one of the things that makes him both charming and compelling. I may be naive, but he strikes me as a decent person. (Actually, all four of them did.) I also love how Binney can't help but blurt out what goes through his mind sometimes, and the geeky passion with which he launches into his plan for how to do things better, if anyone expresses the least interest.
