I don't really like it but it's not really any of my business. That's how I see it. It's not a channel I watch. If creators are crazy enough to pay for having their stuff publicized by a youTube personality then that's really up to them. Personally though I think good quality creations will not need the publicity plus I see other youTube personalities recommend sim creations in their videos all the time and all they ask in return is a view and a like, maybe a subscription to their channel at most.
