I would expect hijinks from the guys at Mandiant or any other exhibitor constituting even tangential competition (or anyone from Palantir for that matter) could include something like that sign. There's something clearly going on that we're not being told - but then again, bear in mind that they're a private company so it's not like there's an obligation to disclose.
