What is the OGL and why is Wizards killing it?

WoTC has had their new OGL leak. With this new Open Gaming License I am afraid they will destroy D&D as a brand. Here I go in depth into the history of D&D and its OGL from the 2nd Edition buy out through the creation in 3rd Edition and its continuation in 5e. Then I show how the 5th Edition changes to 6e or the 6th Edition or One DND as they are calling it. Wizards of the Coast and Hasbro have made a major mistake here and are using fear to bully people out of making content for the games they love. They have killed their golden goose to get at those eggs inside and now the OSR will thrive. Also don't steal or pirate Wizards of the Coast’s products, find a good Third Party RPG like Pathfinder to replace it. Remove their market share.
