Thanks for the link, that's a nice critique. That said, much of their arguments don't apply here. The article take the publisher's ("businesses") perspective, but that's not consistent with a search engine in this case - the original study is more accurate from the perspective of optimizing for the search user. The business wants to convert low-value mobile users into high-value app installers, and would happily sacrifice most to get a few installs if that's net positive on long-term value. The search engine, on the other hand, wants as many users as possible to be successful in finding what they're looking for. These perspectives are not aligned - high abandonment rates due to interstitials can be fine for the business, yet penalized as destinations from a search engine. The underlying question is who Google optimizes for in this case, the user or the destination.
