To you. A review can't (and arguably shouldn't) be everything to everyone. For example, for those who are flexible in the operating system they use, it would make more sense to compare with different manufacturer's products; for those who are interested in using macOS, it the review as written makes more sense. The first sentence of the piece is "I’ve been using Mac laptops for a long time, going back to the very first portable Apple ever made": it's unlikely they're writing to the former audience. You may not be the intended audience, and that's okay. There are likely reviews out there that address the questions that interest you. This just happens not to be one of them.
