Default powerful encryption "breaks the bargain" between citizens and government, argues the head of the FBI.
I'm pretty sure we just this week had it confirmed that you have backdoor capacities to turn on the microphones in like everything we own, which means that encryption of voice calls is useless. Malware that lets you read keystrokes captures data before the start of the end-to-end encryption process, and if you can seize control of the computer you can read the data on the other end anyway.
Besides, encryption is a branch of mathematical logic. You can't ban it any more than you can ban people from doing math. If you made it illegal to manufacture commercial encryption, anyone with a computer could still brew it up if they bothered to learn how. At least this way you can bribe the tech companies to give you a backdoor or to leave vulnerabilities for you to exploit in the system (as the Vault 7 documents claim your friends at CIA have been doing).
If anyone has a right to complain about the bargain being broken, I would think it was the citizenry. The right to be secure in 'person and papers' without your having to get a warrant seems to be fading in this technological age. If there remain ways of defending yourself from intrusive surveillance, good.
