Kinda similar to how the IDF has never been charged with war crimes despite several of their service-members being recorded breaking the law in their Israeli fatigues. It's not that international law was never broken, it's that Israel considers themselves above the rule of law and international bases of morality. That type of behavior absolutely must be called out in it's lonesome, such that no nation ever repeats Israel's embarrassing mistake.
If you know of any other cyber criminal organizations like the NSO, where governments use their tools to select and murder targets, please describe them.
once you meet your first transnational human trafficking ring with full fledged dev teams etc NSO seems very ethical among its ilk if you hear about it in the news its the tip of the iceberg
