I’m confused. Magazines review products all the time that are also advertised in their pages. What’s important is that one is not influenced by the other–that’s why we have “Chinese walls” to ensure that ad team doesn’t know what the edit will be and vice versa. Part of not knowing is that you can’t predict ahead of time when you will in fact have the two in the same issue, as was the case this time. But in such cases we try to avoid any perception of conflict by ensuring that the ad is placed as far from the story as possible to emphacize that the two are unlinked. This is standard practice, and done according to ASME guidelines.

Ads that have their own edit-looking copy are clearly marked “Advertisement” or “Promotion”, as was the case here (I just checked).
