Follow Ghostcrawler's twitter and see where he ends up. If he truly took another job opportunity, we will find out where eventually, whether it be in game design or as a marine biologist. Someone will eventually tell us that they hired him, if he doesnt tell us where he went himself. If we dont hear anything within like a month as to his new employment, then i would say he was forced out. Reading his words, it doesnt seem like he was forced out at all but I could be wrong about this.
