Because mass storage manufacturers have been pulling this scam for a very
long time.  Read the fine print on any typical hard drive manufactured since
~1988 -- you'll find a defintion like "1 MB = 1 million bytes" or "1 GB = 1
billion bytes".  There was a false-advertising lawsuit in the late 1980s
about this, resulting in manufacturers working around the issue by adding
that redefinition of "MB" and "GB".

So, when a mass storage manufacturer says "100 MB", it probably means
100000000 bytes, not 104857600 bytes.
