I don’t think that’s true. They apparently thought that was their business, but it’s not what their customers think it is. And having that much of a mismatch between what you think you’re selling and what everyone else thinks you’re selling often ends very badly.

For example, Kodak thought they were in the business of selling film. Their customers thought they were a company that sold ways to take photos. Kodak ignored what their customers wanted, the ability to take photos easily, in favor of their desire to sell more film. That cost them dearly when digital cameras took over.
