I think their business is ethically dubious but there's an outsize degree of outrage compared to companies like weapons manufacturers. It's the same thing. They make extremely dangerous tools and sell them to governments who can optionally use them for good, evil or a bit of both. You can certainly criticize them for their role in the death of Jamal Khashoggi for example. But he only died because the government of Saudi Arabia wanted him dead. They've also had no trouble acquiring fighter jets they've used to kill thousands of Yemenis.
