Actually it's mainly the hard drive manufacturers. To them 1GB =
1,000,000,000 as you note above. In my experience all hard drives are
spec'ed this way. Of course, most software does the right thing and
report in terms of powers of 2, where 1GB = 1,073,741,824.
Memory, OTOH (and thank heavens) isn't. At least, I've never noticed
being shortchanged on a memory module.
