My personal theory about Atlassian: they have realized (like SAP did before) that once you convinced management to use your product you no longer need to worry about what the users think.
You don't like that the ticket form has 50 fields you don't need? No problem! All you need to do is to convince your manager to contact support and tell them to track less data about your progress. I bet your manager will love that.
And once they got the foot on the door, who is going to convince the company to migrate away from them?
