I think the replies from toasterlovin (below) summed it up on the diff between PR and ads so I'll leave it at that. The root of what you are asserting is that is ANY review is corp PR. Which is partially true - a review (good or bad), and esp high profile reviews, can shift conversations around its subject. For smaller entities, any publicity is good publicity, not as true for larger entities. So if Apple gave a review copy of a phone to a photographer, that based on his past writings, Apple was fairly sure would write something "positive" - they made a good bet and the review copy of the phone paid dividends. That being said, the article isn't corp PR - it reads like a "fanboy" review and that's exactly how I took it. Not an advert. Personally for camera tech I like sites like dpreview.com (no review site is perfect). I did like some of the example photos in this article tho - don't know if I could ever reach that quality but I'm not a pro photographer.
