Seeing the news of Apple using DXVK for the their new toolkit rubbed me the wrong way. I don’t think it’s right that corporations can just use your tools and give nothing back.
Given this, I think it’d be a good idea for DXVK to switch to MPL. I think hard copyleft would probably kill the project, but file based is a pretty good compromise in my opinion.
If I understand this correctly, DXVK uses the zlib license. I could see how it is being too permissive, but I am no expert.
They do, which is why Apple was apple to take their code and close it down.
