Jurisdiction
This is a genuine question. The Feds might think they have jurisdiction over AMZN. But knowing how sensitive people are to where their stuff is stored, would having Amazon regions owned by Amazon GBP 2016 Eire Ltd, Amazon 2016 GmbH or Amazon Cayman Holdings etc make any difference? Surely Amazon are doing something similar to that anyway for tax reasons, or some other more beneficial-but-still-legal financial juggling! I sure as hell would.
Or do the Feds/US Govt just assume that because they originated in the US and listed in New York that all international subsidiaries, even if legally non-connected, are part of the parent?
