I don't think there's even a moral aspect to robot uprisings in most stories. Relatively few sci-fi stories go into detail on why the robots rise up. It's just a way to introduce interestingly different antagonists and conflict into a story, which is the heart of drama, and it has the advantage that robots can get defeated via military means without anyone feeling too bad about it because they weren't human to begin with.

I guess it depends a bit. There is of course plenty of action scifi schlock that is pretty shallow.

But probably the works that most popularized robots were Asimov's stories which very much revolved around why robots do X (although in some ways Asimov's robots aren't just a stand in for otherness but have more of a unique identity relative to other works and isn't usually about uprisings per se).

Blade runner & do androids dream of electronic sheep are very much about what it means to be human.

Battle star galactica (the remake not the original) is another obvious example about otherness and dehumanization of the enemy. So to westworld (the tv show that is).

The non-uprising ones also often are about if the robot has a soul e.g. Data in star trek.
