Some good points in this article and some things that are just not going to work. Imagine you have 100 people working on one product. Lets say that is 10 teams made up of 8 "developers", a product owner and scrum master. We all know that one dedicated product owner on one scrum team of ten has more than one persons worth of work to do. With your model of 1 product backlog = 1 product owner = 1 product increment = 1 sprint review (and presumably 1 sprint plan and 1 retrospective) your product owner will have 10 to 20 peoples worth of work to do. Your model also means that all 100 people are going to be at the sprint review which is unworkable and very wasteful of most peoples time. Also how are you going to develop an integrated UX/UI design and an integrated Technical design across 100 people? I think your scaling model is completely unworkable and you would be far more likely to have success with LESS or Scrum NEXUS. I suggest you rewrite this part of the article
