That is simply not correct; you were being questioned about your travel plans which happened to be a trip through ORD to AMS. It is standard CBP examination: ask questions and see how people react and if the answers make sense. Had you been traveling YYC-ORD-MIA, he might have asked you what you plan on doing in MIA. Would you then consider that a prediction of internal immigration control?
Yes, asking these questions of a citizen and/or legal resident of the US is internal immigration / exit control depending on the ultimate destination?
What if my plane ticket took me to my legal residence in the USA, and the CBP officer asked me if I planned to travel the next day (internally or internationally)? Next week? Next month, next year, next decade, etc? At what point do you consider those questions Soviet-esque? What if the GE or Nexus kiosk asked the same questions?

I'll be using GE, so no consumables coming back on this trip.

That would require a huge investment on the part of the government, I suspect.
I don't think so. Many international airports have international terminals. So put an exit control at the entrances. Solved.
For those international airports without international terminals, most of those have international arrivals halls connected to one terminal. So rope off part of that terminal to use for exit controls. Solved. The investment is pretty much in doubling the CBP airport workforce.
