Hi there. I work at Atlassian. I'll look into this and respond back on this thread. To be completely open, it may be a while before I get an answer since it's just been announced.

For those of you that don't know, Atlassian offers free licenses to open source projects, including cloud and server versions of Jira, Confluence, Bitbucket, and more. See https://www.atlassian.com/software/views/open-source-license... for more info and approval criteria.
