An update:
If your company is on the U.S. OFAC SDN lists, subject to an OFAC sanctions program, or owned/controlled by a company on the list, our ability to collaborate with you will be subject to restrictions, and you cannot be in the MAINTAINERS file.
Linux Foundation (of which Linus is an employee) is an US entity. RISC-V International foresaw this and chose to incorporate in Switzerland.
