I’m confused, are you actually advocating for companies to retain control of their properties forever? Public domain exists for the benefit of all people, to keep knowledge and art open and available, and to allow future generations to build on existing work.

Sure not a huge deal for Mickey mouse because it’s not as important as research work or whatever, BUT considering Disney was literally built on repacking public domain stories (Pinocchio / Snow White / Beauty and Beast directly taken from previous works, Lion King is basically Hamlet with animals), it’s past time they contributed back.
