Not my screenshot btw but I hunted it down after playing through this part. I've been playing it for a bit now (I'm on path C) and it's still not 100% obvious to me that it's an explicitly pro-leftist, though there are some hints. For example, there are also 2 robots named Marx and Engels, where Marx dies early and you talk to Engels as a side quest. I'd love to hear what your thoughts are on this game if you've played it before.
I love that the way Yoko Taro writes makes for a much more repayable game without ever needing to address the gameplay itself, of course the fun combat carry most of the game but the way the story is writing give me that want to play the game again to see in a different perspective even with A/B routes been mostly the same content.
