This question already has an answer here:
I created a Chrome browser extension, and I want to post the code on Github so developers can contribute to the project.
My goal is to keep this as one single project though, and I fear that a lot of nearly identical extensions would start showing up in the Chrome Web Store if I released the code without restriction.
I would like to find a license that:
- Allows modification
- Forbids any distribution other than pull requests back to the original repo
- Gives me (the repo owner) the right to distribute code from pull requests on the Chrome Web Store
I would think this would be a common problem, but I can't seem to find a license that fits. Do any licenses like this exist?
