NSO [...] cannot be held accountable for the actions of its customers
This is an argument that has been used many times - and sometimes successfully - at least in court (e.g. US gun industry).
In some cases that statement clearly doesn't hold (e.g. tobacco industry).
If a company makes a product which has as its sole or at least main purpose the spying on end users (even if it is 'only' governments), it is easy to decide where on the spectrum this case resides.
Facebook's hypocrisy is mindblowing!
AC, because I am not responsible for what my fingers type :-)
