HP Lovecraft was horribly racist, but his works are in the Public Domain. Neither him, his estate or any causes he supported get any money by engaging with his works. His opinions are still part of his works, but that can be criticized and modified in adaptations and derivative works.
The same can’t be said of living creators who still own and profit from those works. Even if some team deliberately tries to gloss over or alter concerning aspects, the money the author gets might still be directed towards concerning movements.
In all fairness there are concerning aspects in many industries and a lot that we consume, and each person has a lot of other issues to worry about, so while disappointing, it’s inevitable that people won’t care about everything. But I definitely don’t feel confortable giving money to someone who’s spreading hate about people I care for. I used to be a big HP fan but this situation completely spoiled any interest I had in that world… and also helped me realize it was never that good anyway.
