They are managed by different standards organizations. One doesn't like the other encroaching on its turf. "kilo" has only one official meaning as a base-10 scalar.
I don't think of base 10 being meaningful in binary computers. Indexing 1k needs 10 bits regardless if you wanted 1000 or 1024, and the base 10 leaves some awkward holes.
In my mind base 10 only became relevant when disk drive manufacturers came up with disks with "weird" disk sizes (maybe they needed to reserve some space for internals, or it's just that the disk platters didn't like powers of two) and realised that a base 10 system gave them better looking marketing numbers. Who wants a 2.9TB drive when you can get a 3TB* drive for the same price?
