companies themselves can decrypt devices, but police cannot.
the model we actually mean is through a secret FISA court, the company can be compelled to decrypt a phone. since the San Bernadino case was bungled --it used real courts instead of kangaroo courts-- manufacturers have no choice but to implement a system where they are no longer part of the cryptographic chain. customers dont care if their data is used by manufacturers in the pursuit of heavy handed capitalism, but theyre more than outraged about the notion that their trusted lifestyle vendors are somehow feeding private information into the hands of a government that has been demonized by politicians for 40 years.
the rules have been written. you cannot have cloud, which is infinite money for rented imaginary property, without security from an incessant police state (or one so perceived.)
