I don’t know that I agree, especially if you used the previous software in a way that caused real harm or loss. Imagine you were a financial consulting firm and I sold you software that guaranteed that you could make 20% per year every year for your clients. But, oops, my software couldn’t do that initially and you lost millions of dollars, garnered a bad reputation, etc. Would it be okay if I eventually delivered an update that fulfilled that promise at a later date?
