Agree with your nit picking completely, most cyclists go with "sealed" meaning unitary bearings with built in races and balls or rods which are pressed in place
and made to commercial standards versus loose balls which roll in races that are either part of the hub/pedal/BB/headset and are held in place by nuts or screwed
in housings. These have seals of course. Terminology.... The pedals in question have loose balls/cups/cones and are not unitary whatever that means

Giggle snort....
