Nope, it is sales' strategy and marketing. As disgusting it is. We are in a capitalist world, for the best and the worst.That's objectively bad writing/design. Objectively. Over 25% of the material provided is essentially irrelevant to the adventure, and apparently suited to a different adventure. Imagine buying a book about the FR and finding 25% of it was entirely about Krynn or something, with no indication on the back or in the marketing that this was the case.
