The linked article makes a lot of assumptions about the "Massive Digital Data Systems Program". It seems this program existed. For example, here is a 1996 paper [1] about research funded by the "Massive Digital Data Systems (MDDS) Program, through the Department of Defense."

But it's not clear that funding for early research into data warehousing (back when a terabyte was a lot of data) has anything to do with whether or not Google uses end-to-end encryption? Lots of research got funded through the Department of Defense.

Without having relevant evidence, this is just "let's assume X is true, therefore X is true."
