Well, well. If you want to encrypt your backup data in the UK you'll have to do it yourself with open tools because Apple have removed encryption from uk backups rather than create a master-key to let the government decrypt everything.
Absolutely the right move from Apple, probably nobody should have been trusting Apple to encrypt their backups and so doing it themselves anyway.
Absolutely the wrong move from the UK government, as usual, who seem to think there is such a thing as an encryption braking key which only good-guys can use.
Even though the cops and the government also contain bad-guys.
Tsk. Seems like governments can't make good internet law ever at all.
