Is GitHub open source?

GitHub is the favorite platform for many developers to launch their open source projects and take advantage of free resources. While the GitHub platform is popular with open source developers, the GitHub software source code is closed. In fact, GitHub encrypts its source code. Although the source code has leaked, GitHub forbids customers from using the code to build competing products.

Why isn't GitHub open source?

A major motivation for GitHub to keep its source code closed would be to protect its commercial interests. With open source software, anyone can audit, modify, and enhance it. Perhaps doing that to GitHub’s software could have a negative impact on the company’s business.

How is GitHub related to Microsoft?

Microsoft acquired GitHub for $7.5 billion in 2018, but has allowed it to operate as an independent business. Many believe Microsoft purchased GitHub with the goal of using it to drive demand for its cloud services. Microsoft and Amazon are the world’s top cloud providers.

However, Microsoft’s acquisition didn’t go down well with every GitHub developer. Some feared that Microsoft could push through negative changes, while some point out that the Windows maker hasn’t historically been a champion of open-source software. The concerns about Microsoft ownership led some users to migrate over to GitHub's rival GitLab. Instead of accepting a buyout from a Big Tech, GitLab decided to go public through an IPO.
