What is the most important difference between generic software product development and custom software development? What might this mean in practice for users of generic software products?

In the case of generic software development, the developer has the control of all the decisions while with custom software development, the client is responsible of the decisions about the characteristics of the software.

This means for users of generic software products that they don't have control over the product.
