Quoted from Coz:
Franchi has absolutely no filter, I like that. Unfortunately it’s not “politically correct” and not fitting with today’s political climate.
It has nothing to do with politics. Stern is running a business and dealing with major licencors. If Franchi leaks art in violation of the terms of a license, or burns a bridge with a licencor costing Stern a deal, then real people suffer. Stern loses money, Stern might have to lay off people. "Sorry you are getting laid off, but our art guy's just got no filter, unlike all the other adults who understand how to behave at work".
I like Franchi's art too but I don't air my company's dirty laundry or petty squabbles and he shouldn't either. It's unprofessional.
