That "famous" quote is out of context nonsense. It refers to the technical changes in how the dev team creates the next version of windows by working directly on the current version. Compare the the past where a copy was uses as the base for a new windows which was developed separately from the current released version. It had/has nothing to do with the name which is a pure marketing decision.
>"Uhh, turns out we can't make that much money off of it"
Make no sense since its still an update and although it has a new name it does not need a new license. Beside that windows consumer license are not a significant revenue source since a long time.
