Not a bug: Google distinguishes between megabytes and mebibytes, and between kilobytes and kibibytes. See the difference between that and "1 MiB in KiB" [1]
Unfortunately around '99 "the powers that be" (NIST and IEC, if memory serves) decided to stop the confusion between SI units and (the usual) power-of-two usage.
Now it's Xebibytes for power-of-two and regular SI units for the rest.
It irks me no end, I'm a power-of-two person. But that's the way it is. (Also floppy disks had it wrong too 1024 * 1000 ... sigh)
You might as well argue the usage of Crackers vs Hackers.
Marketers had already for many years been leveraging the ambiguity to sell things in powers-of-1000 scale (SI uses of prefixes) knowing that much of the market would read them in the powers-of-1024 uses of the prefixes. While standardizing the marketing use as wrong might have been better in some senses, consistency with SI and providing a standard and unambiguous (if new and less familiar) set of prefixes for the useful powers-of-1024 scale was better the status quo at the time.
