This is why things like mandating Apple, Google, et al use breakable encryption is extremely bad. Anyone who follows information security knows Apple struggles to keep up with 0 day exploits.
My opinion is that it is both in the interest of the United States government and all human-rights abiding democratically elected states to have as absolutely secure and anonymous communications systems as possible. I’m not the only one who believes this. In fact, I think this is very very much a CIA vs FBI situation, domestically. Is it really worth exchanging knowing what was on some dead nut jobs iPhone for the ability of government officials, the military, business executives (e.g. Jeff Bezos apparent breach by Israeli assisted Saudis), and every day common citizens to communicate securely?
