9000 people who make products that suck should do something else with their lives. Does that mean they will lose their jobs? Yes. It's still the best outcome for the world and those people will get other jobs, hopefully making better products.
I think you’re confusing your opinion with reality, the truth is Jira (I presume this is your real complaint?) is fine and works well enough for most people they can just get on with it.
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.
