It seems highly unlikely this sort of acquisition is for the technology alone.
=> Extremely steep price

general overview:
http://blog.baha.dk/2015/12/19/part-2-developing-demandware/
I worked with a team which put together a complete ecommerce site using mostly their standard http APIs in a couple of months, and unlike the WCS deployment I dealt with, Demandware was usually working. We did run into plenty of bugs, but the account manager got them resolved in short order.
I would agree that, assuming no other context, Demandware is awful. In the context of its competitors, it feels like a breath of fresh air.
