Honestly, when working with computers, KiB, MiB, GiB, etc. just makes more sense usually. It is easier to reason about address space and page sizes are often delineated in 4KiB chunks. It does come off like "inside baseball" a little but there are practical reasons for it.

If you really want to come at it from an information theory perspective, even the "byte" is rather arbitrary - the only thing that matters is the number of bits.
