Also you need to read the Constitution. Nothing carries a copyright "forever". Everything is supposed to enter the public domain after a reasonable period of time in which the owner has exclusive use (as is the case with patents).
"Fair use" permits some legal use of someone else's work before that copyright expires.
Article 1, Section 8, Clause 8To promote the Progress of Science and useful Arts, by securing for limited Times to Authors and Inventors the exclusive Right to their respective Writings and Discoveries;
Copyrights now are extended for over 100 years. Hardly the "limited time" the founders intended for the "authors/inventors" to have with their creations. Their creations' copyrights now long outlive the creators.
The Founders gave us a "republic,if you can keep it."Now we are told we live in a democracy,and really it's turning rapidly to nannyism.
The original intent of the Constitution is more often ignored than cited by those in gov't.
