In the past few days, an announcement from Red Hat has caused quite a stir in the Linux community. Red Hat, a leading provider of open-source solutions, has decided to put the source code for Red Hat Enterprise Linux (RHEL) behind a paywall. As someone who has relied on Red Hat’s offerings for years, including the CentOS distribution, I find this change both surprising and concerning. In this blog post, I will share my thoughts on Red Hat’s recent source code availability changes, exploring the impact on downstream rebuilds, migration challenges, and the availability of alternative solutions.

Red Hat and the Importance of Enterprise Source Code Availability

Red Hat is a renowned company in the world of open-source software. With a focus on enterprise solutions, they have been a pioneer in providing reliable and scalable Linux distributions. Open-source philosophy emphasizes the accessibility of source code, enabling users to study, modify, and distribute it freely. Red Hat has long embraced this ethos, contributing to the success of projects like CentOS and Fedora.

Downstream Rebuilds and Red Hat’s Acquisitions

Downstream rebuilds refer to the process of taking the source code from a distribution and recompiling it to create a compatible alternative. CentOS, an immensely popular downstream rebuild of RHEL, provided users with a cost-effective and community-driven option to enjoy the stability and compatibility of Red Hat’s enterprise-grade Linux.

In 2014, Red Hat acquired CentOS, further strengthening their presence in the Linux ecosystem. However, the acquisition raised concerns among some users, as they wondered how this would impact the future development and direction of CentOS.

Changes and Migrations: CentOS 8 and the Rise of Alternatives

In December 2020, Red Hat announced an unexpected shift in their support for CentOS 8. Initially slated for an EOL (End of Life) date of May 31st, 2029, CentOS 8 was abruptly discontinued, forcing users to seek alternative solutions like AlmaLinux and Rocky Linux. This decision put significant pressure on users, requiring them to migrate their infrastructure ahead of schedule.

Red Hat’s Latest Move: Source Code Paywall and Its Implications

Just when the dust began to settle from the CentOS 8 discontinuation, Red Hat surprised the community once again by removing public access to the source code of RHEL without any prior notice. This move not only affects downstream rebuilds like CentOS, but also impacts newcomers such as Rocky Linux and AlmaLinux, which rely on RHEL’s source code to provide compatible distributions.

The Importance of Alternative Enterprise Solutions

While Red Hat’s decision to make the source code exclusively available to paying customers is within their rights, the lack of warning and its potential impact on downstream rebuilds is a cause for concern. Enterprises that have already undergone a migration from CentOS 8 now face the possibility of yet another major transition. This sudden change could push users towards exploring alternative options that are entirely free, although without official support.

The Way Forward: Considering Alternatives

Red Hat’s decision has raised questions about the future viability of projects like Rocky Linux and AlmaLinux, which have emerged as promising alternatives to RHEL. These distributions allow users to test software and configurations without requiring a full RHEL license, making them particularly valuable for smaller users or testing environments. If these projects fail to sustain themselves, migrating to community-driven distributions like Debian Linux may become a viable option.


Red Hat’s recent source code availability changes have undoubtedly stirred the open-source community, especially among downstream rebuild users. While Red Hat and its parent company IBM have the right to modify their business strategies, the lack of prior notice and potential disruptions to enterprise infrastructures raise concerns. As users evaluate the impact and explore alternative solutions, it remains to be seen how these changes will shape the landscape of enterprise Linux in the coming months. It could even see a shift in my personal use, as I am currently running RHEL on my servers but have already made plans to migrate to Debian should Red Hat continue to make things difficult for the downstream distributions.
