It's like ranting that people talk about "10mb" files. Or "100gb" or "100GB" drives. When they're technically "93.1GiB" drives ("gibibyte" [1],[2], or [3]).

It used to be common to speak of sizes in "hard drive megabytes". Eventually, the disk manufacturers won the pointless semantic battle and that went away.
In practice, it matters not in the slightest.
