The recent Foxconn plant in Wisconsin that may or may not be happening is a great example. They committed earlier, and claim now that their initial estimates were incorrect and that a plant in that area will not be profitable for them. They have now stopped the plan entirely and reworked what it is they are going to build completely from scratch. This despite having already committed to building the factory.

Even at scale people can pull out of complex agreements if their estimates turn out to be faulty.
