The fact that management and employees give the same rationale for doing a thing isn't evidence of bad faith, because this is also what would happen if there were a good reason, or at least one that looks good to some reasonable people, that both management and employees were convinced by.

I'm not familiar with this case, but if e.g. the reason is "Whatever we do, the Chinese government is going to ensure that any search results its population can see are censored. So our choice is whether they get censored Google search results or censored someone-else search results, and it's hard to see how the first of those can be worse either for us or for them" ... then I don't know whether it's actually a good reason, but it does seem like a reason that some decent and intelligent people might find convincing, even if they have a normally functioning sense of guilt.

For the avoidance of doubt, the opposite position -- "if you do this you're an accomplice to oppression, and 'if we don't do it someone else will' is a lousy response" -- also seems to me one that some decent and intelligent people might find convincing. No one on either side of this needs to be an idiot or a scoundrel. (Though I bet some people on both sides are both, because that's always true.)
