I think the tone is in response to similar hostility from the other crowd. This isn't a new issue, the first time I read debate about the default regularization settings in scikit was a couple years ago. Back then the initial responses of many, including the scikit developers, could be very condescending and strong at times. Its only been in the last year or so that the tide seems to have shifted against the current defaults, and the devs have begun to acquiesce in the form of more explicit documentation, etc.
