What the dude means is, that the development of the game or its content was perceived to be altered by real world social/political concerns. Not that the content itself is about political concepts. IE, MK11 the girls are covered up more, Apex Legends' character roster emphasizing racial diversity, Overwatch altering one of Tracer's butt-centered victory poses, and Neil Druckman of Naughty Dog's public embracing of the Sarkeesian mentality
in a 2013 speech was theorized to have influenced the design decisions that went into Last Of Us 2.
Note I said "perceived." Not "was actually."
