Really what this all boils down to is that some people want to begrudge the fstoppers website for having a silly, fun, interesting idea and running with it, which along the way they received their 15 minutes of internet fame.
They didn't try to hide that they were using expensive light mods, they didn't hide the fact that the stuff was retouched, they didn't hide the fact that there was a makeup artist.
They just made a fun to watch, compelling video which will benefit beginners and bring a smile to non-beginners. Any starting photographer could walk away from that video with some ideas of light placement at the least.
Some people look at things like this and see the negative aspects which for whatever reason compels them to criticize it. Other people look at things like this and see the positive aspects and then have the need to defend against the critics
I lurk in a big way on this site with a little more than 100 posts in all these years. I've learned quite a bit, seen some fabulous work, enjoyed a laugh or two, but I'll never understand the vitriol that is spewed about, even if it's in micro doses.
Criticism for criticism's sake does nothing for anyone, but I guess we all knew that already right?
