I'm surprised it's taken this long for WotC to properly monetize their DnD IP.
To be clear, I don't condone OGL1.1, but the entertainment industry has become a huge multi-faceted monster over the last few decades, where there is a lot of money to be made, and owners of original IP increasingly want to ensure they have a share of derivative income, as well as some control over how their IP is presented by other parties.
Like anything else, if you don't want commercial imperatives to dominate ( WotC and other companies first duty is to their owners/shareholders, not their customers ), then you need to create entertainment content using permissive licences like Creative Commons.
Realistically, this means cooperatively creating new game systems that anyone can build on; the question then becomes, can players and content creators be persuaded to abandon their existing games systems? There is a lot of tribalism and "stickiness" involved, so it is unlikely that players will abandon WotC in droves.
Sad, but probably inevitable.
The thing is, the OGL didn't cover IPs. That's why we don't have 3000 Baldur's Gate/Dragon Lance games right now. Those require a separate license to use from the OGL. Hasbro is attempting to monetize the background systems. While I agree that they should be able to monetize those, I see that as the same as licensing an engine, like Unreal Engine for a game, what they're doing is almost criminal.
