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....
None of the Work may be used in any form as part, or whole, of an
integration, plugin or app that integrates with Atlassian's
Confluence or Jira products.
its just the apache 2 license with a restriction to not sell this project on one marketplace. Can still sell the code elsewhere. Its still totally open source, and honestly Confluence is not something I would loose sleep on. Jira has been a cash cow for a long time, and I have a beef with them anyway
I have a totally different view, if I can use it in my own projects, that are released with an MIT or Apache 2 or similar license, then its open source.
Not that I want to, but I could contribute to draw.io, or fork it and privately make changes, then make money off either the original repo or my fork, and its legal.
I could sell one line of code change for a million dollars and then start writing daily taunting letters, daring them to sue me, and I would be fine.
I think anyone arguing that would eventually fall back to not so defined standards to make their point.
Ultimately, from my point of view, I am a developer who makes software that others will take advantage of to make their own profits.
I have not made any ground breaking projects yet, but I am working on one the past year, and hope to have it widely used. Maybe it will, maybe not
But, my viewpoint is that users are greedy, they want everything for nothing. I also need users to want to use my stuff. Its a delicate balancing act.
I think ultimately, the op source code did it wrong in the beginning, if they had layered their work more, some of it open source, some closed source, they would not have the backlash now.
Maybe one day my own stuff will have similar controversy, or not! Either way, if people call my own stuff not open source enough, and I am looking at my bank account, I do not care
I honestly do not care, there are too many open source organizations doing their own plays for money and influence, honestly, in large, they are the best for progress
But you couldn't release your own projects based on this under pure MIT or Apache-2.0. Presumably you'd need to include the same restriction about selling on Atlassian's marketplace.
