Lapses on that scale are not an engineering issue, they're likely a culture issue. Atlassian are a successful business that sell to engineering businesses, but that doesn't mean their leadership know or care about engineering.

That's the best way of putting that I've ever heard. Stealing it.

Atlassian undoubtedly has very smart people working there, but the absolute cluster mess of JIRA and their other flagships indicates deep management incompetence that favors shiny new feature over cleaning up the mountains of jQuery debt.

Atlassian has the Google problem: buying and half-ass integrating a competitor, shipping new features, that gives promotions to the people involved, but "menial maintenance" is not seen as necessary anywhere...
