Like the other commenter discussed, I think objective when it comes to reviews is a very tricky idea. My ideal solution to it is having multiple perspectives on a game from an outlet, not necessarily in a review score, but in other formats. That's part of what I loved about Giant Bomb, I'd typically like what Jeff did, but might not be as into a Brad or Dan game all the time.
I don't think the idea of objectivity makes a ton of sense at this point, but an authentic perspective can serve that role.
I think a large part of why so many outlets sell out is due to the idea of infinite growth and/or revenue dropping from Youtube/Twitch/etc. taking more of a cut. Ideally this would be solved by remaining small, focused, and less dependent on revenue sources that can change on a whim.
Not the best clip summarizing this episode, but South Park has a great take on this.
