Modification and Enhancement:
Users are typically allowed to modify and enhance the software to suit their needs, and even contribute these changes back to the original project.

Transparency and Collaboration:
The open nature of open source projects encourages collaboration and transparency among developers and users.

Examples:

Open Source Initiative:
