I was asked during a merger, which work management tool do you think we should keep/use? I replied, don't ask me, I'll hate it anyways.

It's not because I hate Agile, Scrum, or even Waterfall (although I do hate SAFe). I just know these tools all suffer from similar drawbacks, and somebody will ultimately codify all our organizational problems into the tool. Then, rather than spend an hour a week of their own time, they'll create a new mandatory field and ask thousands of people to spend an hour a week each populating that field.
