1. Passionate developers often swear more often when they feel safe to do so
2. Developers work better in a "safe environment" where they are not judged / forced to follow other guidelines by social or employment pressure.
And another point : those places where it's unsafe (often due to managerial micromanagement) are miserable places to work. That can drive away skilled developers or suppress them if they remain.
All this is assuming the research metric is real, though I'm not sure it is. If the metric for "code quality" is actually "precision following a coding standard" you'd have though that rigid adherence to procedure would lead to a higher score?
