Edison was ruthless about patents and their reach. There are many stories of him sending men to confiscate camera and film from early directors/film makers arguing he owned the content they created with "his" technology. He also personally claimed the patents for many technologies invented at his firm vs listing the actual inventor but keeping ownership and royalties to his firm like today. He was a titan of inventing for sure and fostered an environment where amazing things were created but would probably be considered incredibly toxic in today's world.
