All they had to write was "It’s been two years since HipChat joined the Atlassian family"... the rest is obvious. IMHO Atlassian is a company focused on helping enterprises control users of their software, not help them. JIRA's maddening UX is Exhibit A.
How is JIRA's UX maddening? It's so highly configurable that it really depends on how it is set up, and what the patterns of use are within your organisation.
I would argue that "maddening" is an understatement. JIRA' ui tries to do so much and allows such granular customization that it takes an age of expertise in the tool to simply properly configure it to your organization. In fact, one of my college buddies job's is exactly that.
