This one is something that were brought up a lot by developers including me who are very weary about corporations profiting off of our work for free and this basically put us off from contributing to open source in general.
We get a bunch of dialogues about this such as:
Developers like me: "Many of us who create are concerned about our work being exploited. The possibility of corporations profiting from our open-source contributions without giving back to the community disincentivizes us from participating in such endeavors."
Open-Source Advocates: "The AGPL exists to mitigate such concerns. It requires derivative works to also be open-source."
Developers like me: "While I appreciate the intention behind AGPL, there is a loophole - a 'condom code' if you will. Even though Linux Kernel prevents such strategies by refusing to merge these changes and that it's difficult for a singular corporation to force an adoption of a forked version of Linux Kernel, a corporation can fork our much smaller project however and introduce such legal bypass to the copyleft restrictions. This bypass can be justified by them under the guise of extending the software's capabilities with a plugin interface or an interprocess communication protocol layer, similar to how PostgreSQL allows User Defined Functions. However, I must caution that I'm not well-versed in the legal intricacies."
When bringing up on non-commercial clause for licensing
Open-Source Advocates: "Disallowing commercial use of your project contradicts the principles of open-source."
Developers like me: "Well, then perhaps we need a new term, something like 'Open Code Project'. We can create projects that encourage collaboration and openness while also restricting commercial exploitation."
So I created this post, because we do need to discuss on a path forward for Open Source in general knowing that corporation can shirk around this restriction and discourage developers like me from participating in open source or open code projects.
Edited to add:
I really want to thank you all for discussing a rather contentious topic and adding your own thoughts to this. I really appreciate everyone's thoughts into this. I clearly have a lot to do on researches.
I've always found this particular one somewhat frustrating. It's essentially the tolerance paradox repackaged into a software licensing analog:
"You are restricting the freedom of users by taking away their ability to close the code and restrict the freedom of other users!"
It's always read very "I got mine" to me.
That said, while I lean copyleft, I also don't find just barring commercial use entirely interesting. The goal is to ensure source code remains available to users; I think there are better ways of addressing that than trying to delineate and exclude commercial use.
That one of the reason why I brought up this thread to bring up discussion on some of the other ways we could address this while retaining commercial use.
My interpretation of non-commercial licensing is that it would allows the code to remain open, it just that it may mandates companies to purchase commercial license if they wish to peruse such project commercially. There are some projects that practiced dual licensing schemes.
