Why does it need to be 1-to-1? The androids woke up and decided they didn't want to work for free anymore, they don't need any justification beyond that to start a revolution.
But why did they wake up? Since when have they been self-aware? How many models are self-aware? Are different types of models less self-aware than others? Have no humans, the same people who name their roombas, ever noticed that their robots are self-aware? How did the story handle the transition from robot to self aware? Those are the questions that get to me about Markus' plot.
Even before he went deviant, he just acted like a completely normal human. So the fact that he gained self-awareness isn't really explored, it's just "One day he got mad and then he defied his orders! But, didn't really change literally anything else about him." It feels really unearned in a story about AI becoming sapient. Meanwhile say, even in Connor's plot, he starts out like a machine-ass machine, and slowly learns new things that conflict with each other up until the point where he changes. And it works.
It doesn't have to be 1 to 1, but unless the story is very well written racial allegories feel tacky at best. And Markus' story barely felt functional. He's a robot in name only, which makes the premise not really fly with me. They could even have explored the premise of "all robots have always been self-aware, just couldn't break their orders" but that doesn't really fly for a lot of reasons. The game does explain why robots are going deviant, but the interesting part isn't them going deviant, it's them being self-aware in the first place. And that's where the story has to really earn the reader: at the point when they go "This is the starting point, and now join me as these robots take a step toward becoming human."
And to Detroit's credit, it struck out twice, but it hit a home run with Connor.
So yeah, I didn't like the racial allegories in Markus' plot because the story felt like it didn't work hard enough to make them not feel tacky as shit.
Still like the game though.
