This model stands in contrast to proprietary software, where the source code is kept secret and only the original creators have the right to make changes.

By providing access to the source code, these programs empower users to control their own technology, customize software to fit their needs, and avoid vendor lock-in. This level of transparency also allows for greater security, as anyone can inspect the code for vulnerabilities or malicious elements. As a result, users are not solely dependent on a single company for updates, bug fixes, or continued support.",

Developers can build upon existing projects, share improvements, and learn from each other, accelerating the pace of technological advancement. The open nature of these projects often leads to higher quality software, as bugs are identified and fixed more quickly by a diverse group of contributors. Furthermore, using open source can reduce costs for individuals, businesses, and governments, as it is often available for free and can be tailored to specific requirements without expensive licensing fees.",
