I agree with the use of kibibytes here.

Standard prefixes and units can and should be endorsed by Policy, or
else we have confusion over what standard prefixes such as "kilo" mean.
The meanings are well defined by both international conventions and
standards, no matter if some people disagree or don't like the names.

k = 10³ = 1000
Ki = 2¹⁰ = 1024

To do anything else would be plain wrong, and make computer
scientists look like retards for using a prefix to mean something
different than what rest of the *entire planet* understands it to be.
