Were you aware of NSA surveilance before Snowden?
It all comes down to trust, and once there is no more trust (like in case of US gov) then the burden of proof they are not doing anything wrong is on them.
NSA has been already caught spying on everyone in the world. The method explained allows them more spying. Would you risk your country security, or your own business relying on a piece of technology that NSA or anyone else can use for spying on you? Given a choice between multiple platforms why would you choose one vulnerable to spying and inherently unsecure?
I don't see why not. The same logic is used by the governments' war on terror. "We're going to detain you and put you on a 'no fly' list until you prove you aren't a terrorist".
