That may be true, but these companies (NSO group is by no means worse than the rest of them, just more notorious) have been caught over and over again, selling these "weapons" to dictators, companies, etc, who in turn use them to spy on journalists and activists, not terrorists or anything of the sort. And that doesn't even go into keeping 0-days for the benefit of the few, keeping literally everyone on the planet less safe, which is arguably as big an issue, if more systemic.
These companies may exist in some form or another because the nation state & private surveillance systems that form their client base want them to exist.
But my point is that the individuals working at this company should be ashamed of themselves. I'm not appealing to their sense of morals, I'm talking purely about "us the tech community" making it abundantly clear that having one of these companies on your CV will make it very hard to find any decent job afterwards. It needs to be socially expensive to work there. To loan from Max Goldt's opinion on the BILD newspaper [1]:
> NSO Group and the like are an organ of infamy. It is wrong to use their products. Someone who contributes to these products is absolutely socially unacceptable. It would be remiss to be friendly or even polite to any of their developers or managers. One must be as unkind to them as the law will just allow. They are bad people who do wrong.
