Attribute	Free Software	Open-Source Software
Licensing	Must allow users to use, study, modify, and distribute the software	Must allow users to view, modify, and distribute the source code
Philosophy	Focuses on user freedom and ethical considerations	Focuses on practical benefits of open collaboration and peer review
Community	Emphasizes community-driven development and support	Emphasizes collaborative development and transparency
Branding	Uses the term "Free Software" to emphasize freedom	Uses the term "Open-Source Software" to emphasize practical benefits

Definition

Free software and open-source software are often used interchangeably, but they have distinct differences. Free software refers to software that gives users the freedom to run, copy, distribute, study, change, and improve the software. This freedom is based on the concept of four essential freedoms: the freedom to run the program for any purpose, the freedom to study how the program works and adapt it to your needs, the freedom to redistribute copies, and the freedom to improve the program and release your improvements to the public. Open-source software, on the other hand, refers to software whose source code is available for anyone to inspect, modify, and enhance. While both types of software share similarities, they have different philosophies and goals.

Licensing

One of the key differences between free software and open-source software lies in their licensing. Free software is typically released under licenses that ensure the four essential freedoms mentioned earlier. These licenses, such as the GNU General Public License (GPL), ensure that users have the freedom to use, modify, and distribute the software. Open-source software, on the other hand, is released under licenses approved by the Open Source Initiative (OSI). These licenses focus on making the source code available for inspection and modification, but they may not always guarantee the same level of freedom as free software licenses. Some open-source licenses may have restrictions on how the software can be used or distributed.

Community

Both free software and open-source software rely on vibrant communities of developers, users, and advocates. These communities play a crucial role in the development, support, and promotion of the software. Free software communities often emphasize the importance of user freedom and ethical considerations in software development. They may prioritize principles such as privacy, security, and user control over their computing devices. Open-source communities, on the other hand, tend to focus more on the practical benefits of open development and collaboration. They may prioritize factors such as code quality, innovation, and market adoption. While there is overlap between the two communities, each has its own unique culture and values.

Development Model

The development models of free software and open-source software also differ in some aspects. Free software projects are often driven by a strong commitment to user freedom and ethical considerations. Developers may prioritize features that enhance user control, privacy, and security. The development process is typically transparent, with decisions made openly and collaboratively within the community. Open-source software projects, on the other hand, may focus more on technical excellence, innovation, and market adoption. Developers may prioritize features that improve performance, scalability, and usability. The development process may be more focused on achieving specific technical goals and meeting market demands.

Business Models

Both free software and open-source software have given rise to a variety of business models that leverage the benefits of open development and collaboration. Free software projects may be supported by donations, grants, or contributions from individuals, organizations, or governments that value user freedom and ethical considerations. Some companies may offer commercial support, consulting, or customization services for free software projects. Open-source software projects, on the other hand, may be supported by companies that use the software as part of their products or services. These companies may contribute code, resources, or funding to the project while deriving value from the software in their business operations.

Examples

There are many examples of both free software and open-source software projects that have made significant contributions to the world of technology. Some well-known examples of free software include the GNU operating system, the Linux kernel, and the Apache web server. These projects have been instrumental in promoting user freedom, privacy, and security in computing. On the other hand, popular open-source software projects include the Mozilla Firefox web browser, the WordPress content management system, and the Android mobile operating system. These projects have focused on delivering high-quality, innovative software that meets the needs of users and developers alike.
