WB/Monolith tried to do something nice for the family and to honor a dev team member in a way that actually allowed people who wanted to donate to contribute directly and receive something cool that celebrated the employee.
This is a pretty new idea for charity, at least through Steam/Xbox/PSN storefronts that take a cut, and it's clear that international charity/promotion law is complicated, which is why you always see a ton of fine print. WB is a massive company, which means they need to protect themselves against violating said charity laws.
The above was always obvious, even before today.
People chose to believe that there were bad intentions and that they were trying to profit off an employee's death, even knowing 1) the above 2) that WB paid to have this DLC created and 3) the only money being set aside lined up with first party platform cuts.
Now, the family will get a flat donation instead of something that scales from Shadow of War players, and we will probably never see anyone try to do a charity promotion like this again through Steam/Xbox/PSN.
This isn't a victory for the Forgey family or for charitable causes, this is a lesson to publishers that they are better off staying away from charity lest they get tangled up in international charity laws and raise the ire of gamers looking for the next thing to be outraged about.
