FUD
FUD: /fuhd/ n. Defined by Gene Amdahl after he left IBM to found
his own company: "FUD is the fear, uncertainty, and doubt that IBM
sales people instill in the minds of potential customers who might
be considering [Amdahl] products." The idea, of course, was to
persuade them to go with safe IBM gear rather than with
competitors' equipment. This implicit coercion was traditionally
accomplished by promising that Good Things would happen to people
who stuck with IBM, but Dark Shadows loomed over the future of
competitors' equipment or software. See IBM.
