Stallman pioneered the concept of &ldquo;copyleft&rdquo; and is the main author of the GNU General Public License, the most widely-used free software license. This is why since the mid-90s Stallman has spent most of his time in political advocacy for free software and spreading the ethical ideas as well as campaigning against both software patents and dangerous extensions of copyright laws. That's why he's probably the best guest we can get on to discuss Russia, China, the US: they're all using copyright, and later admitting they're using it to shut down free speech.
