Because the "EVERYONE would buy this!!" crowd really doesn't have the first damn clue. I used to be like that so I get it, but it will take them a few years to fully appreciate that just because THEY want something, and maybe a few of their buddies want something, does NOT translate into "twenty thousand people WILL buy this".
Feniex and the other manufacturers who say "there isn't enough demand" have a LOT of statistical data to back that claim up. Businesses exist to make money. If there was money in it, they'd be doing it. Period.
+1 . And, as with any idea that anyone comes up with, people generally think that XYZ is a good idea b/c they themselves, either consciously or subconsciously, want it so badly (if they didn't want it, then they wouldn't have convinced themselves that it was such a good idea). And, if something like green truly was in such high demand, feniex would've heard from dozens of its distributors "Hey, I've seriously got a lot of ppl asking me for this."
Theoretically, there are tons of potential applications (since there are cities or states list green as a warning color for certain uses in their V&T laws) but they are very limited. For example, NYS was listed above b/c it's technically a VAS
POV color...i lived in 5 counties in NYS over a period of 22 years, and I can honestly tell you that I've never seen a
POV respond with green (I've only seen 2 green teardrops not in use). Aside from green command beacons, the only other times I've seen green used in the U.S. was on Illinois-area apparatus, where 1-2 lightheads in the front of the apparatus and maybe one beacon on the roof displayed green (never for a
LAW though). Now I'm not saying there's absolutely no use for them, b/c there is a use for everything (somewhere down the road), but you'd be taking the already-limited demand for green and looking at even a smaller fraction of that demand as your "target group/customer"
