No. Go FUCK yourself.

No they are not. They are granting permission to use and distribute their Copyrighted Work. They are not giving you anything.

No: you do not have an independent right to use or distribute the Work.
You have a pre-existing duty to follow US Copyright law.
You are granted permission by the Copyright holder to distribute the work and use the work
YOU DO NOT HAVE A FUCKING INDEPENDENT RIGHT TO FUCKING DO SO. DO YOU GET THAT ZOOMER F_UCKING_ FAGGOT?
