Perhaps so, but that encourages innovation on competing features from other parties. Consider Prime Sense, whose technology started out with the Kinect and ended up as the FaceID sensor in iOS. Microsoft still had a Kinect after the acquisition, and a host of other time-of-flight devices have shown up in the market (Intels RealSense camera, Leap motion), and other companies have pursued TOF sensors in phones using alternative technologies. Just because one company disappears doesn’t mean the concepts disappear along with it. And if they did entirely disappear when the company is acquired, that (to me) is indicative of how well the technology was performing in the marketplace to begin with.
