EFF On Why FBI Can't Force Apple To Sign Code (boingboing.net)
New submitter Kurast writes with this article at Boing Boing: Code is speech: critical court rulings from the early history of the Electronic Frontier Foundation held that code was a form of expressive speech, protected by the First Amendment. The EFF has just submitted an amicus brief in support of Apple in its fight against the FBI, representing 46 "technologists, researchers and cryptographers," laying out the case that the First Amendment means that Apple can't be forced to utter speech to the government's command, and they especially can't be forced to sign and endorse that speech. In a "deep dive" post, EFF's Andrew Crocker and Jamie Williams take you through the argument, step by step. (You can follow along by reading the brief itself (PDF), too.)
But, code is not speech.
Yes it is. This is a legal question that's been settled already by several cases. Here's a quote from one of them (Universal City Studios vs Corley)
Communication does not lose constitutional protection as “speech” simply because it is expressed in the language of computer code. Mathematical formulae and musical scores are written in “code,” i.e.,symbolic notations not comprehensible to the uninitiated, and yet both are covered by the First Amendment. If someone chose to write a novel entirely in computer object code by using strings of 1’s and 0’s for each letter of each word, the resulting work would be no different for constitutional purposes than if it had been written in English.
