The ban has apparently been in effect for years at some of these agencies, if only for the classified networks. One curious twist to this story is that, if we're afraid of hardware from a Chinese company, we should probably be afraid of, um, all gadgets. Pretty much every major tech company manufactures in China, from Apple to Samsung to Microsoft, and though some companies (like Google) are trying to manufacture in the States, the vast majority of electronics still comes from Chinese factories. Are they any more trustworthy than Lenovo? Who knows?
