Law do not exist by itself; it’s the result of balance of power. How would you know that your State do not use illegally free software ? And if you know it, could you sue it ? Even if it’s a classified administration ?
Apply laws Internationally is even worse. It usually depends of the imperialist relationship between States. For exemple, Facebook rules was illegal in France, but France changes it’s laws rather than sue Facebook. A decade later, the whole European Union could forte RGPD upon the GAFAM.
China have nothing to fear in ignoring those licence, and we shouldn’t rely on it to protect our work. However we could strengthen our common defenses, through FOSS for people in the US … and maybe trade unions elsewhere.
I said such things too, but one day I ask myself, could I said it in front of people bombed by my tools ? Our tools are not neutral things, but produce and distribute by social relationship that we could fight. Sorry but we the rise of fascism and ecological disaster we could not afford to give up our power as producer to mass murderer
