I think there's also a difference between the actual reason you leave vs. the reason you tell all your Google friends vs. the reason you post to Medium. You can't tell your coworkers you disagree on politics, so you tell them you wanted to move back home. You can't tell the public audience that the work culture was too hard for you, so you tell them about Google's arrogance or some other thing. A lot of the human ability to rationalize comes from the need to explain your motives to others in a way that endears them to you.
