"End-Use control" is burdensome on any high volume commodity product. Without requiring end-use control there is no stopping a middleman outside of US reach from selling on the products to someone else. This is different from banking as we are talking about commodity parts here. For example, Iranian nuclear enrichment plants allegedly used Siemens controllers, c.f. Stuxnet.
