What's interesting to me about these posts is that usually employees are complaining about their current job, or a very few experiences compared to the thousands of software shops implementing this framework with various degrees of fidelity. While your experience may suck, mine at my company has been pleasant and planning/estimates greatly help us organize and predict our work. We get the benefits of breaking down complex tasks, while throwing out anything unnecessary to us and coming to terms with the fact that estimates != time. Anything the business asks of engineering is a problem to be solved be engineering leaders without decimating the productivity of your teams. I've gone from IC to engineering leadership and while I get the arguments, most of the blame falls on poor engineering culture and management implementing things without thought. You don't have to do everything the framework tells you. Use it in spirit in a way that's appropriate to your current team and company.
