"Python (2.0) applications that are for internal use only and that aren’t exposed to the public Internet could in theory be run indefinitely."

So, IMO, there was absolutely no need to disable Python 2.0 compatibility in Poser 12 and 13 in the first place.

Because last time I checked none of the Python 2.0 scripts that I'm using for decades now had ever any buisiness connecting to the internet, anyway.

(Nor has Poser itself, but that' another story)
