There is no shift happening what-so-ever. They're hiding the offensive spending for plausible deniability purposes, and to keep some information from US enemies. It's trivially easy to shift expansion in the cyber offensive spending to the black budget segment, so US enemies can't get a clean idea of what the US is spending or not spending in that area. The US does this as a matter of routine in defense spending, and has across most of the post WW2 era.
