I want to know the answer to the following question:
What does Stallman think copyright was supposed to trade temporarily for public benefit?
All the background I'm provided with is that "Still referring to copyright, he cites legal literature such as the United States Constitution and case law to demonstrate that it is meant to be an optional and experimental bargain that temporarily trades property rights and free speech for public, not private, benefit in the form of increased artistic production and knowledge.". Is that enough to answer the question?
Answer: yes
