I could not disagree more with Atlassian. They are among the best software i have ever used. Especially bitbucket is superb. Confluence is by far the best wiki I have ever used. Jira is 10x better than any alternative I'm aware of.
Bitbucket is an acquisition that was decent before the takeover. Jira: How hard can we make it to manage bugs? Jama: How hard can we make it to navigate the document tree?
