I don't think that's how it works. Yahoo went all-in with China and has significant staff and hardware and user records located in Chinese jurisdiction. Once you make that initial mistake you're basically fucked when it comes to resisting the Chinese government, because they'll just throw your people in jail, or confiscate servers.

In America there are appeals processes, so Yahoo could avail themselves of those.

So Yahoo may well have had a consistent "fight for the users" policy, but were constrained differently in different jurisdictions.
