The purpose of this site is to maximize the time users spend looking at the content. The problem lies in that you think the content is the article, when it fact it is the ads. Once you take this into consideration, this is an excellent layout.
But if they want more impressions, they should let us read content first. If I like the content, I'll surely follow their recommendations for sharing and ads.
If you want to find out these kinds of answers for yourself, try running an advertising-supported website for a few months — it could be genuinely interesting.
In the long-term, I would expect that for you to continue to enjoy quality content on qz.com, you'll probably be disappointed by an increasing amount of advertising. Whether it's in-between scrolling articles, or in the form of advertorial, or a banner at the top of the screen, it will come :( Such is the way of the world.
