Incorporation in Switzerland has the effect of calming concerns of political disruption to the open collaboration model. RISC-V International does not maintain any commercial interest in products or services as a non-profit, membership organization. There have not been any export restrictions on RISC-V in the US and we have complied with all US laws. The move does not circumvent any existing restrictions, but rather alleviates uncertainty going forward.
Countries by definition are not neutral. Switzerland is an odd special case, but even they're not truly neutral. European perspective may be different by I've always considered the US to be relatively neutral in legal senses. There's a strong backdrop of rule by law in the US.
