All the ideas related to the question are good and demonstrate it’s not an easy question to answer. I think that as robots continue to become more prevalent and diversified, the answer to the question will become less important.
Consider: what is a computer?
We could all present our definitions that would probably vary slightly. Then the questions would follow: is a smart phone a computer? How about an iPad, Echo, Nest Thermostat, autonomous car, smart watch, Fitbit…?
Suppose some authoritative organization declared that smart phones should not technically be considered “computers”. Would we suddenly see them as less valuable?
As robotics advances I think we will be able to notice the “robotic” aspects of devices and be less concerned as to whether or not it should truly be considered a robot (I’m already there…).
