Yes maybe metaphorically, if not literally. The company who is doing a hostile takeover is referred to as a black knight. Generally, a black knight is a company that makes an unwelcome takeover offer for a target company which they don’t want to accept. While a white knight is a friendly investor who advances a friendly takeover offer that enables the target company to avoid the hostile takeover. These both although does opposite work in order to gain the target company, but anyway they make the target company lose its independence.
