Actually....
The term backdoor is considered "sinister", the correct term is "government mandated public security feature". This is a bit like a car seat belt or an air bag, except that it restrains your private life instead of your physical body.
Must give the Chinese double extra propaganda points, though. Can't wait to see how long it will be before the "unbackdoored" phones start catching on. I think its time to put one on the Christmas list.
