Rocky Linux, launched by CentOS co-founder Greg Kurtzer as a replacement RHEL-compatible distro, announced Thursday that it believes Red Hat’s moves “violate the spirit and purpose of open source.” Using a few different methods (Universal Base Image containers, pay-per-use public cloud instances), Rocky Linux intends to maintain what it considers legitimate access to RHEL code under the GNU General Public License (GPL) and make the code public as soon as it exists.

“[O]ur unwavering dedication and commitment to open source and the Enterprise Linux community remain steadfast,” the project wrote in its blog post.

The Software Freedom Conservancy’s Bradley M. Kuhn weighed in last week with a comprehensive overview of RHEL’s business model and its tricky relationship with GPL compliance. Red Hat’s business model “skirts” GPL violation but had only twice previously violated the GPL in newsworthy ways, Kuhn wrote. Withholding Complete Corresponding Source (CCS) from the open web doesn’t violate the GPL itself, but by doing so, Red Hat makes it more difficult for anyone to verify the company’s GPL compliance.
