Less than six months later, Redhat announced that the were going to discontinue RedHat Linux and start releasing their new RedHat Enteprise Linux. This left me rather angry and embarrassed. It was definitely a turning point in my understanding of FOSS. It also made me a lifelong Debian/Debian derivative user.
I've supported RHEL professionally, even getting RHCEs in it. RedHat has also contributed a lot to the open source community. But I've certainly never forgot that first pivot, so I'm not surprised with their recent decisions regarding RHEL's source code.
