How is it a retcon? The use of giga- as a prefix for 109 has been in use as part of the metric system since 1960. I don’t think anyone in the fledgeling computer industry was talking about giga- or mega- anything at that time. The use of mega- as a prefix for 106 has been in use since 1873, over 60 years before Claude Shannon even came up with the concept of a digital computer.
if anything, the use of mega- and giga- to mean 1024 is a retcon over previous usage.
