What is socialist about GPL?
Being forced to open source seems like a pyramid scheme. Better examples of socialist and libertarian politics are licenses like MIT or BSD. They embody use without damage.
Stallman seems to have a flawed understanding of hierarchy and power. He exhibits such in the infectious GPL and pedophillic political takes. I purposely avoid GPL or derivatives when considering libraries.
Banning ownership becomes a game of catch. Use whatever you have: 7.62x51mm, arrows, rocks, ect.
