it suddenly occurs to me that the push to abandon the 3.5mm audio jack could, in part, be an effort to close the analog hole. Right now, you can take any device with a headphone jack, plug it into a laptop with a microphone jack via a plug-to-plug audio cable, and obtain a decent-quality DRM-free reproduction no matter how encumbered the source file or player happens to be.
@diodelass They're still making adaptors with 3.5 mm jacks. Should they stop doing that, it wouldn't be particularly difficult to extract the analogue signal from a pair of sacrificial headphones. Maybe they are trying to lock things down, but it won't work. It never does.
