I remember the term "Public Software" used several years ago from the Lula's initiative to migrate Brasil public software infrastructure to Free Software.
Now there is, again, and effort to discuss the term, this time from a Anglo-centric perspective. Native English speaking people, particularly in US have the trouble with free as in freedom and as in "gratis", meanings and being immersed in a "market first" mentality, usually they think first in price and markets instead of rights.
Dmitry Kleiner has addressed the problem of software as a commons and its sustainability with an alternative license (p2p license), that is not as restrictive as the Fair Software one, but it repolitize the capitalist friendly Open Source gentrification of the original Free Software movement, involving also a core concern of sustainability.
Would be nice to see a dialogue between Nadia's and Dmitry's perspectives and questions about software as a commons.
