Even if you think I'm wrong (to which I highly recommend you ask some other people, preferably strong developers, as the idea that this is difficult for Apple to build isn't me "estimating" here, it is the kind of idea that should be discarded at the face of it as it is so absurd... this is something they could assign an intern to and it would still be done in a few hours), then we are just talking about some different time period for someone to build the software here: whatever it is, it is fundamentally insignificant in comparison to Apple spending a few minutes to use their key and sign the firmware. The world isn't somehow different once that software exists, even if you think it is hard to build: what is fundamentally different is only that people realize the government might be able to force Apple to use their key.
