Plunk, It certainly would be if I was selling the Project Management software (my product) to perform Accounting functions. In other words, if I try to make my client believe that the product I sell is something that its not - then I'm a bad guy. And the buyer should beware. Same with a river. If I buy land on the river, I darn well know that the river I see today can be totally different tomorrow. If I don't know that, then what I get I may deserve.
