Hi valneq,
First of all, thank you for notifying me of this issue, it will be fixed right away. Although the icon is just a forum/mod decoration and nothing else regarding gameplay, I do confess its design was oversimplified at first, especially after having to deeply understand how Bob's libraries work to safely implement this mod extension.
The focus of this mod is to provide alternatives to all players who are not satisfied with the existing processes in Bob's mods. I believe it will not only be a valuable & positive feedback, but also a reason for people playing more Factorio with Bob's mods. I'm a very experienced programmer with over 25 years of programming, and also a huge fan of pure Bob's mods with hundreds of hours of gameplay. I simply won't release anything which could harm the gameplay or the challenges provided by Bob's mods: even after installing the mod, it does nothing until the player accesses the mod settings and specifically enables the desired settings.
This mod contains absolutely NO copy of source code or resources provided by any other mods, unless strictly allowed by the previous code/resource owner. I am being careful here, so I can safely say it should not be offending any existing license.
Furthermore, I have chosen the most flexible and permissive license available for this mod, because my main goal is actually to contribute to Bob's mods. In the long run, I do expect Bob to integrate the most popular changes, while this mod 'extension' remains as a lab for the most controversial or non-standard changes.
I personally believe there is absolutely NO POINT in restricting the license of something which is not allowed to be sold commercially anyway, especially a mod of such a great game. The intention with Bob's mod extension is to improve gameplay of Bob's mods, providing valuable alternatives to the player, finally making people play Factorio with Bob's mods installed more than ever before.
