I'll find out if this is true. Hiking buddy of mine pointed it out on Friday, so got one on the way. Was $18 when he called it out, $23 by the time I ordered. Apparently they have a bunch of random stuff like this. They must have some outdoorsy folks in marketing.
Thru hikers just kind of find this stuff. They are obsessed with weight and recommendations spread quickly through word of mouth on the trail and on forums.
And sometimes there are items that flare up and get popular before disappearing, leaving stragglers to scour second-hand lists. I remember people talking about CostCo ultralight quilts and similar.
Mine came in at 288g, which is a bit more than the 280g that the article mentioned. The nightcore NB10000 w/cable comes in around 167g. Will see this week how it does from a battery performance perspective.
