There's only one mission I remember where you engage with any sort of revolutionary rhetoric. It's the one where you're tracking down hidden messages calling for an overthrow of capitalism. Johnny's there commenting, and despite how he's supposed to be this militant revolutionary himself, he completely mocks the hidden messages. He goads you to find the rest and where they're coming from, I think he says they're probably written by some dumb angsty kid. I thought it seemed really out of tone, but now I realize the game's writers completely missed the point of the setting.
Then again I'm losing faith in cyberpunk as a genre to begin with. William Gibson turned out to be the biggest liberal on Earth. Mike Pondsmith doesn't seem much better.
