I never implied that Italian framebuilders were extinct.

Most of those listed in your post are boutique brands, those that aren't have probably abandoned Italian threading.

Look, I personally love Italian steel bikes but I am just saying that you shouldn't be aghast that a component manufacturer may want to phase out old and unnecessary standards. Especially when they really haven't. FSA seems to be making the bottom bracket you need but primarily for the European market. Did you see the link I posted above?
