I'm indeed surprised and I'm sure there are other cases like this out there, it would be interesting to know the thinking behind it.

In my experience of working with big corps, if you are using Jira and Confluence, Bitbucket simply offers much better integration with them and lately Atlassian is rocking it with new features and deeper integration every time.
