The interesting question is whether it was a mistake. Just because it was eventually rolled back, doesn't mean it wasn't worth it to win the large customer.

I once worked with a CEO who would always answer "Yes" to questions about whether the product did something, much to my horror as Director of Engineering.

Mind you his approach actually seemed to work - people would ask things in sales meetings then you'd never hear of that request again. It only went wrong in one sales meeting where one person realised what his approach was and started asking for sillier and sillier things....
