No forking/reselling takes place (unless of course that is desired by the product creator). The only role Git plays is first-class support for developers to do things like:
1. Do a "git pull" to get product updates instead of having to go to some online UI (like CodeCanyon) to get a zip archive, then manually do a diff to see what changed. And my favorite thing is you can add the git repo in your package manager (like npm or composer), which none of the other product platforms allow.
2. Creators can make releases (like GitHub does them), which is very cool for managing release-specific issues/bugs, handling subscriptions per-release, or allowing customers to get updates only when you're ready for a release.
As far as compensation goes for any collab done related to this HN post, I'm open to any suggestions. My main goal is to find creators, not to profit from the collaboration directly. Mostly just looking for fun creators to work with and willing to help them any way I can!
