That would be "oversubscribing" - and yes, that's definitely something that ISPs do a lot of. ;)As for terminology, coming from an ISP and hosting environment overprovisioning to me means selling more than you actually have, like in bandwidth, CPU cores, memory
For the phrasing on SSDs I believe it's a matter of perspective and the frame of reference - the manufacturer overprovisions their SSDs by adding extra NAND (applying more than necessary). We as end-users underprovision by limiting addressable space (using less than provided) with the central frame of reference in both cases being the factory-usable space out of the box.
