Oh, it absolutely is.and you think that cyberpunk is not about the power relations between individuals
But something being about politics does not make it political.
For example, a neutral documentary about the civil war in the USA is not political, despite being about politics.
It would become political if it was taking sides or recommend actions as a lesson from that.
The game does not take a value judgment on almost anything, and it most certainly does not prescribe a certain behaviour.
You are totally free to LIKE the way society works in Cyberpunk, and you can even express that in many dialog choices...
Maybe that is nitpicking about the meaning of "political".
But your description of the game was very close to the definition of sociology, and then you turn around and say THAT is the definition of politics. Which it is not
