For the most part, I agree. But... If the UX wasn't garbage I'd defend it, too. It has a lot of nice features and integrations. But the UX changes they have made in the recent past (few years-ish), made it worse, for me. And, in my opinion, the reason some other company hasn't come along and toppled it: critical mass. It's the same reason Epic is king in the hospital IT world. The UI/UX can be garbage (and it's so much worse with Epic than with JIRA), but organizations will still stick with it, because it's what they know.
