# FAQ
(These FAQ are for reference only and are not a part of the license above)

### Why isn't VRCFury fully "open source"?

For a project to officially be "FOSS" (Free and Open Source Software), its use must be unrestricted and unencumbered,
essentially meaning that it can be used by any person or company for any purpose (sometimes with limited restrictions).

We are not using a FOSS license because:

1. We want to prevent malicious avatar creators from modifying VRCFury and introducing it as an "exclusive" paid part of their avatar
   products. Not only would this be... evil, it also would cause these versions of VRCFury to diverge, preventing components
   made using one version from working on the other version.
2. We want to prevent corporations from taking VRCFury and making it a part of their game without asking. VRCFury includes
   a lot of novel unity logic which would be valuable to a VR or Desktop game company, and if they "took" all of our work
   and made it a built-in part of their game, the development priorities likely would shift toward monetization (as most
   companies do), rather than what's best for the users of VRCFury.


### Can I use VRCFury for an avatar that I sell?

Yes! As long as you do not distribute VRCFury itself along with your avatar package, you are still totally in
compliance with the license. Simply instruct your users to download VRCFury from VRCFury website.

### Why not use GPL / AGPL?

GPL can discourage commercial use by forcing commercial users to open-source their own applications using such a library.
However, this adds a lot of complexity in our case, as neither Unity nor the VRCSDK are GPL-compatible. Even with special exceptions for these,
we also need to allow custom non-GPL avatar scripts to interact with the VRCFury API, as well as other integrations. Without a way to give separate
permissions specifically for commercial use, there's not a good way to allow these exceptions while still achieving our
goals above.
