That's why I said "usually acceptable depending on the context". In spoken language I also don't like the awkward and unusual pronunciation of "kibi". But I'll still prefer to write in KiB, especially if I document something.

Also If you open major Linux distro task managers, you'll be surprised to see that they often show in decimal units when "i" is missing from the prefix. Many utilities often avoid the confusing prefixes "KB", "MB"... and use "KiB", "MiB"...
