DISNEY CORPORATION and the U.S. Congress are both in massive violation of U.S. Copyright Law.
According to the foundation of ALL Copyright Law, Article I, Section 8, Clause 8:
[The Congress shall have Power . . . ] To 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.
VIOLATION #1: Congress only has the power to keep things out of the public domain AS LONG AS IT IS PROMOTING (NOT LIMITING) positive artistic expression. That is the OPPOSITE of what they and the CORPORATIONS like DISNEY that have possibly bribed and threatened them have been doing for DECADES.
VIOLATION #2: "Limited Times" - the Founder's intent was to make Copyright protections for just long enough to give an individual a fair chance to publish and establish a work before a rich and corrupt CORPORATION or person could steal their work and publish it and claim ownership themselves...a period of not more than 28 years in total. That is far more than enough time for an author to have established his work.
