Every company I've worked at that followed some sort of rigid scrum process has suffered from burnout and general failure in one form or another

It treats developers like consultants because it's really designed for agencies working on one-off short-burst projects ( this is the only setting I've seen it have a positive effect )

by nature it just chews people up if it becomes a day-to-day practice, the whole process revolves around the assumption that there's lack of trust and team cohesion
