The paragraph you describe criticizes some of the characterizations in the game and a lack of options for character customization, both of which seem to be safely within the ballpark for game reviewing. The reviewer clearly has an anticapitalist perspective, but I don't think that's sufficient for "political activism". Reviewers always have some kind of perspective that affects what they emphasize and de-emphasize.
