Tinfoil Hat or Human Nature?
For many years before Snowden I've been predicting this. The usual response was to label me a conspiracy-freak crazy and dismiss me with "why would the government want to spy on my phone/web surfing/e-mail/TV/etc.?"
My answer was simple. Because They Can. Add in a profit or means to control others and it becomes inevitable and imminent. There is always one or a few who will do anything, no matter how onerous or horrible. If ten thousand people recoil in horror before a prospective action, the ten thousand and first will happily do it. You won't sell phone-hacking software to oppressive governments? Okay, but Cellebrite will.
So moving on, apply this simple question: can it be done? If the answer is Yes, someone is already doing it. Wikileaks et. al. only provide confirmation.
