Corporations tend to act morally only when doing so aligns with their profit motives.

You can disbelieve this, of course, and I assume the internal protesters did disbelieve it or at least thought the tech was dual-use (I don't know what Nimbus actually is). But assuming it's true, and also assuming for the sake of argument that Israel is guilty of genocide, I think it raises an interesting question: do otherwise genocidal governments still need and deserve the right to buy civilian infrastructure to support their own people?

I think they do, and that depriving them of that infrastructure could itself rise to the level of a crime (if taken to an extreme).

And yet the IDF and other security agencies in Israel are proudly boasted of as clients in their own press releases.
