Certainly not. Its about removing the jack to make the phone slimmer or more aesthetic or more waterproof. Or all of the above. The internal DAC is certainly part of a SOC anyway.

The point is that having an Apple DAC in a dongle makes no fundamental difference from a DRM perspective over just using the internal one on old phones. Its not a plot. We're in Texas here, hearing hoofbeats and everyone is insisting that zebras are coming.
