>A company complying with the laws of the country it does business in seems fairly uncontroversial to me, even if you may not agree with those laws.

Depends on what those laws are. Imagine if Google was deliberately helping out with some genocide to make a dollar? And given some stories coming from China, that isn't exactly a what-if situation.

>Do you want your companies to be extensions of US foreign policy?

They have to be extensions of US morals to the extent voters don't push for them to be punished for not being so. That's a byproduct of using democracy.
