True. I had to setup Jira for our team and must say it was an awful experience. Too many options, hidden in unintuitive places, awful (too verbose) documentation... Everything is just so difficult. Horrible UX. But it was still the best on-premise solution I could find. Trello on the other side is a delight to both setup and use.

I think buying Trello was great move for Atlassian. No way could Jira compete with them in the long run. And now they are even safe(r) from new Trello-like competitors. Brilliant move for Atlassian. Too bad for us users... :(
