I come from a xcountry background; with a wide range of alpine skiing experiences over the last 25 years.
IMO/IME- fat skis have a variety of applications in xcountry, alpine, telemark, and XCD touring.
IME- a "fat" ski has at least three primary applications:
1) flotation in deep soft snow
2) stability on extreme slopes (both turning and climbing)
3) dramatic sidecut profiles for downhill turn initiation/completion in a wide variety of snow/terrain conditions
As already mentioned by others above, extra width coupled with the myriad of potential camber, flex and sidecut combinations lead to an almost limitless variety of skis designed for every imaginable skiing context: snow, terrain, boot/binding tech, skier ability/style, etc.
I most certainly agree that I have seen an incredible number of people with insanely expensive extra-fat, reverse-cambered, powder skis on groomed resort slopes.
That being said; I do have a pair of fairly fat- but very stiff, traditional single-cambered- "all mountain" alpine skis with dramatic sidecut. These skis would be useless in deep, soft powder- but I can literally burn a strip off an extreme slope on dense, hard, and/or icy snow. IME- the stability offered by a fat ski on extreme slope cannot be underestimated.
However- IME- I need some pretty rigid boots in order to effectively control a fat ski on a hardpack slope.
There is no question that skis with parabolic sidecut are easier to turn than those without. If you read the history on the development of Nordic (xcountry, telemark) and alpine skis; apparently it was Norwegian xcountry-mountain (i.e. telemark) skis that first had sidecut. Alpine skis did not have significant sidecut until very recently.
Extra width- IME- definitely offers better climbing efficiency- with more width/traction under foot.
Nordic skis. IME- in North America we have this impression that alpine skis have the greatest range of variability and design. I do not believe this to be true. Nordic skis (i.e. free-heel) cover everything from high-performance groomed-track racing, to 300cm Finnish forest skis, to big mountain telemark- and everything in between. The range of ski designs in the world of Nordic skiing is almost mind-boggling.
XCD (i.e. telemark) touring. IME- fat skis have their place- for the same reasons as previously mentioned. Whether your skiing preferences are towards maximum turning efficiency; or maximum touring efficiency- there is thankfully a wide range of designs to choose from.
Xcountry skiing. I used to be somewhat of a "traditionalist"- long, skinny and double-cambered all the way. I say "traditionalist" because there are few people outside of Scandinavia and Finland that fully understand the incredible range of xcountry ski designs for specific snow/terrain conditions (I do not count myself as one of these experts). What I do know is that "classic" "long" (i.e. to 215cm), double-cambered skis do not perform in very deep, soft powder snow. For example, xcountry skiing in deep soft snow; my Madshus Annums (109-78-95mm; single-cambered), at 195cm, outperform every traditional, 210cm, double-cambered ski I have ever tried. The Finns apparently use extremely long (up to 300+cm), narrow, single-cambered skis ("forest skis") for skiing on very deep snow, on gentle terrain. I understand the length. As a xcountry ski-the only I thing I could ask for more from my Annums is an even longer length!
So- I do think that the use of ultra-fat, reverse-cambered powder skis is grossly overrated- especially by consumers who simply buy expensive equipment regardless of whether the technology is suitable for the intended use.
However- I would hate to go without my stable, fat, traditional single cambered, xcountry and XCD/telemark skis- when I need them!
In particular- I hate to see people being scared off fat xcountry skis- when they really need them to truly enjoy xcountry skiing in deep, soft snow.

Cross-country AND down-hill skiing in the backcountry.
Unashamed to be a "cross-country type" and love skiing down-hill.
