Ganymede Systems
Ganymede Systems was the energy corporation that existed in the far future. One of the resources they mined and sold was copper ore mined from an asteroid by the station Chasm Forge. They manufactured technology and equipment such as the smartsuits used by their workers on Chasm Forge. They charged credits for oxygen.
Ganymede Systems didn't value human life over productivity. Thus when a mining station was not producing enough, they reprogrammed the smartsuits to terminate the organic components. Thanks to the intervention of the Twelfth Doctor, two of the workers were saved and were dropped off at the main office to "give them Hell". As a result, Ganymede Systems was overthrown in six months, thus ending capitalism in space. (TV: Oxygen)
