I'm suprised they didn't mention kibibyte. (Edit: they did) There are plenty of applications where power-of-2 alignment are useful or necessary. Not addressing that and just chastising everyone for using units wrong isn't particularly helpful. I guess we can just all switch to kibibytes, except the HDD manufacturers.

We can, but we won't. At least not any time soon. For the foreseeable future, kilobyte will remain an ambiguous term, and kibibyte will very often not be used when someone is referring to 1024 bytes.
