Maybe we should ask Snowden how far America has gotten into this?
Me, I find this really disturbing that they could be listening to your every call. I've heard that in Saudi Arabia for example, they can find if you are doing anything obscene in Skype vidcalls and arrest you, which is only possible if they are actually watching you or recording those call.
Though we might say it's for security purposes, just the thought that someone is always listening, watching, is just chilling. Who knows when they'll use the littlest things against you or if some corrupt technician would sell your data? Looks like George Orwell is still right, we could still have Big Brother.
