This was designed to fit with internal Facebook frameworks and network capabilities. The device itself does not do much, in most cases just starts a browser and points it to an internal webapp. The device is just the presentation layer of a great deal of backend work that can't be easily extracted as a product.

Still, I'd take that over some shitty "slap a $50 android tablet on a wall and point it at our weird http site" -solution.

Presumably it was envisioned as an internal project, so nobody though about trying to sell it: pure inertia.

Maybe some version of the innovator’s dilemma? The product would have to be insanely successful for it to move the needle at such a large corporation.
