I'm honestly a little confused here. For starters, the "X considered harmful" clickbait title that doesn't actually talk about X but about a certain use of X to sell you an alternative tool feels weird. I also don't think that "focusing on tasks or issues daily" is different from "not getting the right stuff out the door". That's just a problem of how you use the tool, isn't it?

But I honestly don't see the fundamental difference between this tool and, say, my Gitlab issue tracker. Not just from the home page but even going into the guide. You have work items, Gitlab has issues (funnily enough, I was just reading before that Gitlab is migrating under the hood to "work items" to integrate issues/epics/incidents into a single entity), both can break down a single item into multiple ones, have a collaborative document at the top, an activity feed, roadmaps, labels... I don't what's the feature that would make me migrate development workflow to yet another tool (with more costs possibly, because 100 work items doesn't look like much if you deal with multiple projects).
