Google's original rational for exiting China was to protest suppression of information. Has it done anyone any good? China simply developed their own search technology in house to replace Google, but with censorship. By doing so, they strengthened their local tech talent, and now they might outsource the technology they developed to other regimes. If Google had developed this tech from the beginning, they may have been able to avoid letting this tech get into the hands of regimes even worse than China.

Of course, we will never know the alternative outcome. And I appreciate the value of a company standing for moral principals even when it goes against practical considerations. But I think it is highly reductionist to suggest that yours is the only or "obvious" moral view on the situation.
