...using detectable encryption technology like PGP, Tor, VPNs and so on, lights you up on the intelligence agencies' dashboards.... http://www.theregister.co.uk/2016/01/27/nsa_loves_it_when_you_use_pgp/
When more and more people will start using those technologies their dashboard will be filled with lights and they will have troubles separating casual users from dangerous one.
That article is aimed at kindergarten pgp users. There are many ways to communicate using pgp that are outside of clearnet and leave no meta data traceable passing through the various snooping gateways. They would snoop/catch a gmail user trying to send vanilla emails that are pgp'd, but are true bad guys that stupid? Yes, thankfully.
My take is that this is at least in part, sheer fud. Even if consumers don't use strong encryption like pgp, business use is inevitably increasing. It's in the interests of the TLAs to spread fud about encryption, Tor etc, so they will.
