Partial to your partial. Yes, ethanol is hygroscopic, but only to a point. Once it has reached its stable azeotrope it doesn't pull any more moisture out of the surrounding environment. What moisture it does attract it holds tightly to it, which is why it's a component of gas antifreeze/dewatering solutions.
None of those "certain plastics" should be involved in any fuel system sold in the United States after the late 70s, as regulatory compliance required all vehicles be compatible with E10 (which is all you're going to find in standard gasoline, E85 is a different story). Same for ethanol susceptible rubber and foam bits. 10% isn't enough to damage brass or other metals even with constant exposure; they get more damage from the various chemicals found in -all- gasoline than they do the 10% ethanol fraction. Ducati tanks in question were poorly designed and infused, with ethanol getting the scapegoat treatment.
