Yes, strictly speaking, we didn't "have" to because we have many other clients and projects, the company will surely stay afloat. However, we have to because this deal is less and less attractive over time compared to other projects and the management would eventually fire the client (we won't get fired since there are other projects) - before that, the head of the project should at least attempt to talk with the client and try to raise the price (plus there are obvious lock-ins for a giant software project and they can afford the price).
