Also, going online in a 30-minute-plus, point-for-point response to forum posts and Kotaku dreck, that's just not a reasonable business practice.
But there's no reason to expect Dyack to start acting like a reasonable businessperson at this point. Silicon Knights had its last major hit on Gamecube with Eternal Darkness, or maybe MGS: Twin Snakes. That's a long time ago, and time since has been filled with many accusations and finger-pointing. This guy took a bunch of canuck tax money, and used it in a business which stole code from Epic after suing them for that same code being deficient.
There's two sides to every story, but it'd be a cold day in Hel (Norse mythology joke!) before I signed any contract with him.
