I had no idea this issue had been identified. While I find this tool very useful, the project is seeming rather questionable to me now.
For me the problem is more in GPL violation: they distribute blobs under GPL3, user made a request of the source code by creating an issue, but they ignored that request. It is not only about “you have to fix it” versus “just fork it” imo.
Licence doesn’t apply to the creator.
He already owns the copyright, he doesn’t need a licence, he doesn’t need to adhere to the gpl
The binaries in question are various GNU and FOSS tools from elsewhere, not part of the Ventoy project itself. So no, the Ventoy author does not own the copyright of the tools in question.
Even then, he’s still allowed to provide binary blobs. He doesn’t have to provide it as source code. If that was the case, we’d all have to build from source and package managers like apt, dnf and flatpak wouldn’t exist.
All he has to do is make the source code available, i.e. just link back to the original Github Repo.
