This is the sort of thing that gives rise to using flickering backlights to reduce brightness because it's 10p cheaper per unit :/
But if FALD isn't that much more expensive, it seems a real shame that the premium makers - Dell, NEC and the like - aren't using it. If they were prepared to promise BLB-free screens, I'm sure that they'd increase sales...
I heard the difference was 50p, so let's not EXAGGERATE!

(actually, even the 50p difference might have been between 150Hz PWM and 3kHz PWM -- though that doesn't imply that PWM-free solution would be that much more expensive, either)
But in all seriousness, from the business perspective:
When the economies of scale come into play, there's actually a big profit to be made if you can squeeze even 10p from one area, and 50p from another, and so forth (*). But the benefit only stands if all of the manufacturers are on board with skimping it out, which effectively forms a cartel (which is illegal). But it takes only one manufacturer to use the better solution and market it correctly, which ends up them taking the customers to themselves, while the cartel either tries to drive the non-cartel competitor out, or follows their example, when they notice that the cartel has crumbled.
(*): In economics studies, one famous example they teach of skimping out is the big airline company which noticed that by taking out just the peas from all their long distance flight dinners, they saved millions per year. But if you skimp out too much (take away the steak?), then that risks leaving a bad taste (

) to the customers, and losing them to the competitors.
Furthermore:
In case of LED PWM, it might indeed be that the manufacturers genuinely thought that it wouldn't cause any problems, because CRTs were mostly operating at 60Hz, and the LED PWM was around 150Hz. They just didn't factor in the "cooling time", or lack of it. And it's not like PWM is totally useless. For one, it enables a wider control range for brightness, and from what I've understood, allows a lower power draw, as well.
It's just a shame that manufacturers took so long to accept the fact that the compromises were so detrimental that people were even prepared to pay extra for a PWM-free solution. But fortunately, since 2015, it's now more common for new monitors to have a flicker-free backlight than not.
So next in line (my own wishlist):
- scrap the integrated speakers, save some costs
- scrap the TN panels (at least the 60Hz models!)
- include FreeSync/Adaptive-Sync in all monitors
- 100Hz+ for all monitors (this won't happen for a long time)
As for FALD, the extra cost might not be the only reason manufacturers are keeping their distance. From what I've understood, FALD also brings some extra chassis thickness, and some manufacturers seem to have some sort of fixation on avoiding that one. I wonder how long it takes for them to figure out that most people don't actually care that much for an even slimmer chassis. Or that they certainly won't pay much extra for it. IMO, the transition from CRT to LCD already brought enough slimness. Anything after that is just fluff. (OTOH, I do like the slim bezels... - though not enough to compromise on the important features)
