People who really want <whatever>, will <whatever>.
Read somewhere that communication takes place on web accounts where someone writes a message and leaves it open without finishing it. The party for whom the message is intended logs into the same account, sees the open message and does whatever with it. No need for encryption and it will take major effort on the spying party to get to the information they seek. Especially when that is done on random intervals on different locations. No need for encryption and hiding in "plain sight", so to speak.
And those UK parliament nitwits want access to encrypted traffic (customer-bank communication, communication between different energy companies and customers, etc)? Aren't there national lawyers in the UK to fight for prevention of (digital) identity theft by criminals and/or government? Note that I still make a distinction between them, although I am not so sure I should nowadays.
