I think the main takeaway of the review is that for a major Gamepass title, the value of a review is decreasing. The grasp on exclusive access that reviewers held onto in years past that elevated their opinion over the average gamer almost doesn't exist now. They may play the game 2 weeks before you now, but that's it. They used to be the only ones to get games free, but now the consumer practically does as well. There's no actual barrier to trying it.
If the title is basically free for subscribers on day one, then obviously you should play it. In fact, it's actually better to play it yourself and just make up your own mind, because Jeff is saying your own ability to assess the game is equal to his ability. He's not better than you, and that's what this review is saying.
It's just kind of a commentary on the nature of his job changing, and how he has to find new ways to remain valuable to his audience.
