This controversy has been settled in law for a long time.
"The first-sale doctrine is a limitation on copyright that was recognized by the U.S. Supreme Court in 1908 and subsequently codified in the Copyright Act of 1976, 17 U.S.C. Â 109. The doctrine allows the purchaser to transfer (i.e., sell or give away) a particular lawfully made copy of the copyrighted work without permission once it has been obtained. This means that the copyright holder's rights to control the change of ownership of a particular copy end once that copy is sold, as long as no additional copies are made. This doctrine is also referred to as the "first sale rule" or "exhaustion rule."
