 gnu general public license v3 0 commercial use

The GNU General Public License version 3.0 (GPL-3.0) is a free software license published by the Free Software Foundation (FSF). It's designed to guarantee freedom to share and change software while ensuring that all derivative works remain open-source under the same license. Here are some key points about the GPL-3.0 license:

### Key Aspects of the GPL-3.0 License:

1. **Freedom to Use**: Anyone can use, study, and run the software for any purpose, without restrictions.

2. **Freedom to Modify**: Users can modify the software and release it as long as they adhere to the GPL-3.0 terms.

3. **Source Code Requirement**: The license mandates that the source code must be made available. If a user distributes binaries or modified versions, they must provide access to the source code or instructions on how to obtain it.

4. **Copyleft**: GPL-3.0 is a "copyleft" license, meaning that any derivative works must also be licensed under GPL-3.0. This ensures that all modified versions remain open source.

5. **Patent Clause**: The license includes terms that prevent contributors from filing patent claims against users or developers of the software, protecting the open-source community.

6. **Protection Against DRM**: GPL-3.0 includes clauses to prevent Digital Rights Management (DRM) from restricting the software's use or modification.

7. **Compatibility with Other Licenses**: GPL-3.0 is compatible with other open-source licenses, but combined works must be licensed under GPL-3.0 if any GPL-3.0 code is used.

### Common Use Cases for GPL-3.0:

- Used for software that needs to stay open-source even when redistributed or modified.

- Ensures that derivative projects remain accessible to the public.

- Often chosen for projects that value community contributions and collaboration, while maintaining a copyleft policy.

### Licensing Requirements:

When using or distributing software under GPL-3.0, it's important to:

- Include a copy of the license.

- Make the source code available.

- Notify users of any modifications made to the original software.
