Making advanced technology disappear

Most people have heard a variation of a story like this...
A major technological breakthrough threatens the oil industry.

One of the oil giants acquires the technology from the inventor and makes it disappear
(or makes it disappear by other other-than-legal means.)

This is not a "conspiracy theory." It happens.

Here's a case of GM buying the controlling shares of one of its suppliers, selling their shares to an oil company and the oil company making sure a major, game-changing breakthrough never saw the light of day.
