This is just factually wrong. Cyberpunk largely originated in literature and the oppositional stance to existing power structures and hierarchies is absolutely endemic to the genre. If you claim to be making a "cyberpunk" game just cuz it looks kinda like Blade Runner and you make a game that celebrates existing power structures then you are making kitsch.
I would say for the most part, modern cyberpunk is mostly concerned with opposition or negative portrayal of a power structure -- not necessarily one that is currently existing. You could the two most common ones are anti-corporate power, which is a response to an existing power structure, but if you look at other takes on cyberpunk (e.g. the recent highly dystopic Deus Ex MD), they responses to potential existing power structures (e.g. MD evolved from past Deus Ex games to include more response to authoritarianism).
So I think it could in theory be fair game for a cyberpunk to explore other political ideologies or movements. Cyberpunk often explores existing social problems, too: urban density or urbanization; social policies; etc.
As these things evolve since the 70s I think cyberpunk should evolve to consider what happens if new ideologies and their utopian ideals because dystopic.
However, I think there has to be some rooted 'existing' believability to it. There could be some broader liberal power structures that could be explored.
Feminism in particular, though, is still such an activist cause and so far yet away from being a power structure that it seems a unbelievable choice for cyberpunk because feminism is still basically difficult to believe as the power structure rather than the
punk. Feminism
still is the punk. (Though, I mean, it's a free country... if that's what he wants to explore or portray than have at it). Choosing it does feel someone as a personal reaction to it rather than a societal reaction to it -- which is what cyberpunk typically explores.
But there could have been a choice other than just capitalism or authoritarianism. To explore more social-based institutionalizing could possibly work. In some ways, it could be even more
punk precisely because it's such an outcast notion of what exists today as utopian ideals.
