He definitely should not be surprised but he might actually have an argument that the mod is more analogous to an emulator (which are legal but are still shunned by the industry) that simply transforms the display of the content than a mod that deals with the existing content of the game.
He has also tried to make the argument stronger by supporting more and more games to make it more like a generic framework. Some questions do remain on how exactly he has done the modifications though as something as small as fixing existing shaders while reproducing a part of the original might bring you over to the derivative work territory anyway.
Can’t say for sure who’s right here but there’s at least a reasonable argument. The game companies obviously have a different view so ultimately this would need to be resolved in court as there’s insufficient precedent too. I guess for understandable reasons he’s just rather backing down when these complaints pop up and keeps modding other games from companies that haven’t yet issued a takedown request.




Nice, having this in KDE would definitely be a great option to have besides the limited number of other ones.
