Countries do apply sanctions to one another, and that’s directed to the governments not it’s people. is a video game development software that has nothing to do with governments. How are game developers/artists involved with these at all.
If it was a software government even wanted to use, or any government related company wanted to use, then it was easier to understand the IP block. But the governments probably haven’t even noticed Epic has blocked access to their engine as they have nothing to do with it at all and I doubt US laws have anything to do with individuals (us artists) nor they expect that because it doesn’t affect anything but making some people switch to other game engines. But what do I know… let’s see what happens.
