Official Entry: "Politically the Technocrats' philosophy is really no different to the Extropians, except they are a little less colorful and more skeptical of technological solutions to social problems. They believe in a structured and ordered society which rigidly adheres to laws and punishes corruption. They draw most support from the smaller corporations and the populations of the mining colonies."
The Technocrats are completely useless for X-COM. They will be favored to side with whomever is against their enemies, the Extropians.
