GitHub's Shift from 'master' to 'main': A Closer Look at the Motivations and Consequences

GitHub made a significant change in August 2020 by replacing the default branch name from ldquo;masterrdquo; to ldquo;mainrdquo;. This change was officially announced to foster a more welcoming environment for developers. The transition required updates to documentation and user interfaces, as well as providing guidance for renaming existing branches.

Official Motivation

The primary reason for the change was to create a more inclusive and welcoming environment for all developers. The word ldquo;masterrdquo; has historical references to slavery and Nazis, which some argue is not appropriate. GitHub's aim was to remove these connotations and encourage a more positive community.

Alternative Views and Backlash

While some supporters argue for change based on political correctness, others have raised concerns about potential implications:

Political Correctness and Imagined Sensitivities

One view is that GitHub is catering to the ldquo;extreme leftrdquo; and possibly influenced by environmental, social, and governance (ESG) investments or initiatives from organizations like BlackRock or D.E.I. backers. Some individuals who are not as politically active argue that the term ldquo;masterrdquo; should be kept because it references the traditional term used in software development.

Supporters of the change point out that ldquo;masterrdquo; has historical ties to slavery and Nazism, and thus it should be renamed. However, proponents of the term ldquo;masterrdquo; suggest considering the etymology of the word. The term ldquo;masterrdquo; is commonly used in many contexts to denote leadership or expertise. Renaming it could potentially cause confusion or unnecessary technical issues.

Technical Considerations

Technicians argue that changing the default branch name to ldquo;mainrdquo; is unnecessary and indeed detrimental. The ldquo;masterrdquo; branch is merely the default branch that Git checks out after a clone operation. The text file ldquo;HEADrdquo; in the Git repository points to the ldquo;masterrdquo; branch as a default. Simply renaming it to ldquo;mainrdquo; or any other term would not alter the function or operational behavior of the Git repository. Yet, doing so for imagined political correctness and causing potential issues to a vast number of software systems that rely on the expectation of the ldquo;masterrdquo; reference is a questionable move.

Impact on Productivity and Use

Another argument against the change is that individuals who fight for political correctness in software projects are often not productive contributors to those projects. They are more focused on enforcing their views rather than contributing positively to the project's development and maintenance. This shift might also reduce the adoption of the updated version by developers who prefer the term ldquo;masterrdquo; for its traditional significance in software development.

Conclusion

In conclusion, while GitHub's shift from ldquo;masterrdquo; to ldquo;mainrdquo; is driven by noble intentions to promote inclusivity, it is important to weigh the potential benefits against the potential downsides. Technical experts advise against changing the default branch name for political correctness, as it may disrupt existing workflows and introduce unnecessary complexity. The community should look at the practical implications of such changes and focus on maintaining a balance between inclusivity and technical functionality.
