ISPs Removing Their Customers' Email Encryption
Before the conspiracy theories start, I think this has less to do with mass-surveillance and more to do with stopping spam. As hinted :  "Some firewalls, including Cisco's PIX/ASA firewall do this in order 
  to monitor for spam originating from within their network and prevent it 
  from being sent."

When faced with a large volume, companies usually aim for the quickest fix in lieu of the best. And I couldn't help notice the bigger problem here :  "Adoption of PGP has been slow because of its highly technical 
  interface and difficult key management." 

When non-technical people are involved, the number of technical people who dismiss or downlplay this offhand is getting annoying. In fact, just the other day, the replies to this : https://twitter.com/SwiftOnSecurity/status/53081882403604070...Surely, there's a simpler way to manage keys and send/receive encrypted email with PGP or something better?
