They can call it what they want, that doesn't make it right. Slip rings are just that, rings with a continuous contact surface that provide a slip connection (generally in pairs). A commutator is segmented (think of your starter motor). Old cars with a "generator" or "dynamo" had a DC generator and DID have a commutator. An "alternator" is actually an AC device that is rectified to DC through the diode pack in the rear end. AC machines produce an alternating current (hence the name alternator).
