They remind me of screen caps from someone's Fallout 4 mod. They're nice to look at, but at the same time they do look over-manipulated and fake.
I'm only an interested amateur, not a professional photographer. But if you want to pick one of the photos from that article, I'll explain how it was created, to the best of my understanding, and how one might go about creating something similar without any need of multiple exposures or Photoshop trickery.
But all of that is no less "trickery" than the photoshop and bracketing/HDR is - not that I would call any of it trickery.
It's an aesthetic choice, and it's fine to disagree with that, also.
Perhaps "trickery" was a poor choice of words. Until very recently, I haven't really had much involvement or interest in photography since being taught the basics on a Nikkormat FTn in childhood; as a recent amateur armed with a low-mid-end DSLR and very little idea of what on Earth he's doing, I have to say that the modern photographic hobby, at least in its online exponents, seems in many quarters very much more concerned with hipsterism, gear fetishization, and tearing one another down, than with anything that seems more directly involved with actually taking pictures at all.
While I have very little respect for this sort of attitude, I do try where possible to avoid needlessly antagonizing anyone and I suppose the possibility exists that I might at some point need to get along with one of these sorts of jackasses, and so I'm in the process of refining my vocabulary and fashion of speaking on the subject in order to meet that need should it arise. 'Trickery' is the sort of word I'm under the impression such a person would use in similar circumstance, and so it managed to slip out here as well. Such errors will cease as I get this rather unpleasant style more accurately dialed in.
