I think there's a defensible case that in the case of Saudi Arabia, there are other parties operating in the country who are much worse for the rights of both Saudi citizens and humans elsewhere, and selling the digital equivalent of arms to the Saudi Government isn't inherently evil.

I'd sure rather deal with the current Saudi Government than with Al Qaeda. Yes, there are fairly bad elements within the government, and it is at best one of the more restrictive regimes in the world, but there are some alternatives that are worse.
