To reframe our Commitee discussion on this point in the “freedom to run”
(FSD) instead of “no field of use restriction” (DSFG/OSD) context:
Consider, as I described, this happened:

>>> Additional Permissions can be removed by anyone to return to pure GPLv3).
>>> Would it be reasonable to say that GCC team had added a “field of use”
>>> restriction to GCC? If not, why not? 🤔
Would it be a restriction on freedom to run, since downstream could no longer
run the program for *any* purpose, they could only run it for the purpose of
compiling GPL'd software? If not, why not?
I don't claim that I have obvious answers to all this — my point is that the
Committee is finding it useful to challenge the assumptions of past
philosophers. IMO, seeking better, different, and more refined a priori
arguments for the OSD/FSD is extremely useful when considered new modalities
of software that didn't exist when these philosophical documents were first
