>>40621142TL'DR for a big legal doc and 20+ years of history
Wizards of the Coast under Hasbro is making an updated license for their new DnD edition there are two big parts.
1. All projects that make over a certain amount have to pay a fee and that wizards can use your ip if they want.
2. The older version of the License made in the early 2000s when Wizards was an independent company was made with the intention to let others use certain aspects of DnD systems into perpetuity.
The reasoning was to stabilize the fragmented TTRPG market under a consistent set of rules (that also benefited them by basing it off this own game).
This was a clear intention made in good faith by the company at the time and has been restated multiple times by the people who originally made it.
Wizards is trying to use a small portion of wording to overturn the legitimacy of the original License which in turn would force every company who built their IP on the original license to give wizards a 20% minimum cut of profits and would allow Wizards/Hasbro to take whatever they want from the IP's in question and sell it for their own.
