For what they are now – some people find them weird, and would rather deal with people than with robots. I’ve also seen reports that people tend to abuse robots in general and humanoid robots specifically. I guess, they just trying to discover the boundaries of how you ought to behave with those robots.
Futuristic films and games may give you a somewhat distorted view of humanoid robots looking and acting almost like people, but not quite. It’s a useful plot device, seeing how many people fall for it, and how many ethical problems it surfaces. However, looking at humanoid robots that can actually do some work as they are now, they still look pretty robotic. You can certainly distinguish, say, Pepper robot (https://en.wikipedia.org/wiki/Pepper_(robot)) from a person.
So, we end up with “robots will have consequences as far as you design them”. It’s also the question of who will buy enough robots so that they are “introduced” into society. It’s not like we can just dump a whole bunch of them on the streets, and thus, all of a sudden, humanoid robots are everywhere.
