I review articles for an NPG journal. I have seen articles submitted that are essentially advertisements from a company. They don't bother to read the journal's guidance to authors or anything else. I don't see how promising to publish a review alongside that is a good idea. They're just looking for free press and you're rewarding their bad behavior. No one will see the review. They'll see the glossy reprint the company hands out at their booth at the conference, with your journal's emblem on it. I'm not against companies submitting articles, far from it, actually. But how am I going to confidently review a single spaced PDF? I don't even have room to jot notes. I am against a complete lack of respect for the process.

In a case like that, my advice to the editor is not a review, it is to simply reject for failing to follow guidance to authors. Now, it may be that other journals have a better desk review process before sending out to reviewers, but I don't know.
