Back in the 1970s, Kodak tried to give $25m to a black civil rights organisation in Rochester, New York. The company's shareholders rose up in arms: making this politically charged offering wasn't the reason they had entrusted Kodak with their money. The donation was withdrawn.

When someone takes their existing business and tries to transform it into something else - they fail. In technology that is often the case. Look at Kodak: it was the dominant imaging company in the world. They did fabulously during the great depression, but then wiped out the shareholders because of technological change.
