We’re talking about business. To many people, those other companies are conducting legitimate business in China, not committing a clearly inexcusable crime, like your example. Google is competition with those companies worldwide, and it could easily be construed by shareholders that their refusal to participate is harming the business. A clear case can be made that choosing to not participate in the largest market in the world for moral reasons is not a good business decision. The comparison you’ve made fits the situation poorly but I’d welcome a better analogy.
