No country's people should be blanket stereotyped. That's my first instinct. 'why are people from xyz nation more likely to be associated with(negative thing)....'. nah, fuck that kind of talk.
Oh well, each individual must be judged on their actions and merits, but this doesn't prevent us from observing how groups behave on average. Nobody ever shouted racism when it's said that French are chauvinistic or that Germans follow rules strictly- it won't and shouldn't tell you anything about single individuals but you know there's a grain of truth in the generalisation.
Where did you see me saying that? I didn't even mention any people or generalize that all of them are this or that. Saying that cyberwarfare companies are more likely to be in Israel, which is what I did, seems like the most objective way of framing my observation. Other replies already gave some good reasons for why that may be, and all of them have to do with the systems built within the country, not some inherent property of their people. They could change these systems if they wanted to, it's not inherent to them.
