@akeefer nailed it. This is an essay about why project management is bad, written by someone who it seems like has never actually studied project management.
Good planning and estimation is the tool of the worker, not of management. It keeps pointy-haired bosses from coming in and asking "is it done yet?" When done properly, it help justify the number of resources that will be needed to deliver the project on time, and the amount of cash/resources that it will take to complete the project. Good project management results in a not-to-exceed date that is 90% confident (only 10% of projects will exceed this date), so the team has time to tackle unknowns that pop up along the way.
And, yes, at the end of the day, project management is a tool for accountability. Like it or not, everyone has to be accountable for their performance at the end of the day, whether as parents, life partners, or employees. Saying that you don't want to be held accountable by some stupid boss is naive and unrealistic.
If you have a stereotypical corporate antagonistic divide between workers and management then I completely agree. Good planning and estimation is about managing upwards and managing expectations.
If you are in the context that this post was about, with no or very little divide between management and workers, where blame for delays or praise for being ahead of schedule is equally or nearly equally shared among everyone it's quite a good essay imo.
