Secure leaders do not need to stockpile arms, nor do they need to forcibly suppress their dissidents (which is what I understand is the main market is for NSO Group's tools.)
Well that can be more of a factor of what their foreign policy is / situation is and less about internal legitimacy.
Maybe better said they don't need to stockpile arms for domestic use as much if they feel secure / legitimate.
I would think that the different national intelligence agencies would have high interest in infiltrating such companies.
I bet in general non-governmental companies, especially with distributed offices, distributed sales teams, are especially easy to hack/infiltrate.
But NSO Group's target has never been other countries, it has been focused on helping governments infiltrate their citizen's and opponent's phones, which is a much softer target.
