[$] Free software during wartime

Just over 27 years ago, John Perry Barlow's declaration of the
independence of Cyberspace claimed that governments 'have no
sovereignty' over the networked world. In 2023, we have ample reason
to know better than that, but we still expect the free-software community
to be left alone by the affairs of governments much of the time. A couple
of recent episodes related to the war in Ukraine are making it clear that
there are limits to our independence.
