Interesting article. Our PO often almost demands estimations from us. Usually I am already responding in a best/worst case fashion. In the end PO only seems to remember the best case and takes it as commitment. Since I was fooled by this a few times, I am now collecting a paper trail and am quiet reluctant, when giving "just a ballpark figure". My key takeaway was, that estimations mostly aren't about accuracy or getting a value, but rather managing people's expectations and navigating corporate politics.
