Sounds like a money grab, everyone wants a chunk of the pie,
Part of me hates to be snarky but... well, duh!
Nobody here is under the impression that anyone is interested in using the D&D brand in movies for moral, ethical, or charity reasons. Of course it is about money! This is the movie industry we're talking about!
Thing is, Sweetpea is doing a lousy job of making money with the brand. Their movies have been crap. Their last one couldn't even make it to the big screen. They would be well served to hold on just long enough to get a larger settlement, and then get the heck out of the way and let someone else (hopefully, someone better driven and competent) to handle it.
