Dude, a “1.44MB” floppy disk was 1.38MiB once formatted (1,474,560 B raw). It’s been going on for eternity.
It’s inconsistent across time though. 700MB on a CD-R was MiB, but a 4.7GB DVD was not.
RAM has always, without exception, been reported in 1024 B per KB. Inversely, network bandwidth has been 1000 B per KB for every application since the dialup days (and prior).
