I started to consider it a show show way earlier than 18 months ago. Jira is so terrible to use that it is hard to phantom how they are able to be paid for their product

Jira is how it is because almost any product that grows to be that flexible will develop the same problems.

They failed to rearchitect it to something suitable for the inherent flexibility though, so it remains a disaster area, but one that is uniquely able to fit the whims of any manager that can then mandate it for everyone else.
