For the sake of a Devil's Advocate and assuming Disney aren't filthy liars, could this be due to demographical breakdown, with Hasbro knowing that the vast majority of that 14 million are a bunch of low income adults that are consooming the latest media property and nothing else?

Even with 14 million viewers, if I knew that the demographic was overwhelmingly a bunch of people who aren't going to touch action figures, not an unreasonable belief considering most hardcore adult fans that would collect the toys are done with SW, and most kids don't give a shit about a dying franchise, regardless of how much some soulless corporation pumps money into it, from before they were born, then I too wouldn't be making these things because the obvious point is "who the fuck is going to buy it".

Of course Disney is definitely lying, possibly even to the point of lying to Hasbro too, but even that lie wouldn't translate into toy sales because as Hasbro has said there's a lack of demand. The only people watching this tripe is middle-aged losers chasing their youth though consumption. They've become the equivalent of soap opera watchers, religiously watching their low quality dramas with religious fervour, but very little financial investment.
