A robot isn't just software: the hardware for humanoid robots has proved quite difficult to build and if these robots have the hardware necessary to walk around and manipulate objects (in the real world, not in a lab where they get multiple "takes") then they are remarkable even if their every action is directed by a human.
Also I would have guessed that Hasbro owned the IP for robots named "Optimus". Maybe Tesla paid them, the way that Verizon paid Lucasfilm for the right to use the word "droid".
