"When developing a software to compete with Facebook, an iterative approach is more suitable than a sequential approach", why?

I would think that since facebook is already established, mimicking its features is like achieving static requirements

In my opinion, since Facebook is already established, the iterative approach helps developers to gain feedback on how their iterations compare to Facebook. A sequential model is not very helpful for developers to deploy a final product to compete against Facebook.

Also keep in mind that replicating the exact functionality of an existing product is not a good way to compete with it.

Also since Facebook also pushes out frequent updates, using sequential approach would produce a outdated version of Facebook by the time it is released
