Big problem. People will generally stop using phones of which they suspect that they are back-doored. At the same time, it would be a hopeless endeavour for law enforcement to get a swarm of (Chinese or other Asian) companies to help with unlocking their phones. They would literally not even answer the phone. Therefore, this may very well spell the end of highly centralized, Apple-style companies that can be effectively pressured and browbeaten into "compliance".
