Are you struggling to understand the battle between Apple and the FBI over iPhone encryption? Or perhaps you’re having trouble explaining it to a non-technical friend? In this 18-minute video, HBO’s John Oliver lays out the entire case, explaining the details and what’s at stake. Impressively, the piece gets everything right at a technical level and even captures the nuance in the positions of both sides. It’s also pretty funny, but be aware that Oliver uses some strong language (this is HBO, after all). Don’t miss the fake Apple commercial at the end!
