From today the license applied to the project will be the Apache 2.0 license with an extra line forbidding usage of the codebase as an integration or app to Atlassian's Confluence or Jira products....
The license must not restrict anyone from making use of the program in a specific field of endeavor. For example, it may not restrict the program from being used in a business, or from being used for genetic research.
So as far as I gather, it’s still just as open source as before but you just can’t sell it on the Confluence marketplace? Seems fair.
