I'm always very confused about this kind of statement: "Don’t estimate". To me, projects without estimates tend to take way too much time. It's also federating a team to have deadlines. But I agree that estimations often become a joke when your manager asks you to estimate something that you have no idea how long it will take.
How to reconcile both? Being more flexible on the estimation? Taking them as a team goal and not a business one? How to manage the lack of estimation when company planning is important? I can hardly see how "Ok everybody, we are going to release a product but we don't know when! Soon!" could work.
