"In the old days" (TM), manufacturers used to use the terminology
gb
to refer to a decimal gigabyte, and Gb to refer to a binary gigabyte.
(Note the capitalisation of the letter G)
So 180gb = 170Gb was a true statement.

By being legally correct!
The prefix giga has an internationally understood meaning, defined by
SI, which uses a decimal base.
This meaning is used for pretty much everything outside of IT, and
predates the invention of the microprocessor by some time.
A better question would be "how does the IT industry get away with
using technical terms incorrectly and just assume that it can make
giga mean 2 to the power of something".
