Spoiling Linux Kernel with "sanctioned" code

A Linux kernel developer from Russia submitted a bug fix for the USB OHCI stack but was unable to get it merged because kernel maintainers refuse to communicate with contributors from sanctioned countries due to legal concerns about sanctions compliance. The situation creates a paradox where the patch "spoils" the codebase—the exact fix cannot be implemented in the same way, forcing alternative solutions and preventing others from adopting the original code, even though the technical fix itself is sound and beneficial.
