The impact on China's mass surveillance capabilities is negligible, because RISC-V work is open source already.

What the foundation avoids by moving to Switzerland is fragmentation of their ecosystem due to US foreign policy decisions.

Note that China is already among the technology leaders in the world. Even if cut off from the remaining world, they would have no issue in manufacturing and operating sophisticated surveillance infrastructure. So I can't see how the foundation would help suppressed minorities in China by staying in US.
