Except for unfortunately because of popular conventions the SI unit names are ambiguous with the power-of-two unit names. Maybe your point is that no one should have used "kilo" prefix to describe 1024. And yes that would've been great. But they did and now it's very much standard and expected to describe kilobytes as 1024 bytes. So now we are stuck with the ambiguous terms that the SI standardized on. Those are consistent with the meanings of other Greek prefixes, but if the standard unit can be easily confused with another standard, it's not as useful.

Counterpoint: disk sector sizes are not multiples or clean fractions of 1000, and it's unlikely to change anytime soon because we'll likely store files as octets of binary information (binary digits) for the rest of time.

It makes no sense to count it in 1000-based SI units. You'll perpetually mis-align the data in whichever underlying storage technology you're using, and it's bad for performance and resource consumption.
