Okay, we can quibble about the exact qualification. But I, like many others, am often quite upset about all sorts of stupid inefficiencies of Jira, and, to give a nod to a sibling thread: Bitbucket even more so. Now, you say "fine", I say very mediocre. And the thing with developers and their tooling is that we're often quite spoiled such that this mediocrity just doesn't sit well with us. In a lot of places, there is choice such that we can pick the most efficient, non-mediocre tools for our taste. But Jira is just such a de-facto industry standard, that there's less tolerance for shopping around, and many of us get stuck with it.

If you're in a sluggish enterprise, and you're conditioned to sit on the phone for a change request, or wait a minute and a half for your IT website to load, sure, Jira may be a breath of fresh air. But for a lot of us, Jira is the IBM of project management: no one got ever fired for buying it, but few people are happy with it either.
