I don't think anyone's arguing that Red Hat isn't in the right, legally, to do what they did (anymore). At this point, I think Redhat users are just tired of being jerked around. We're not children, most of us in the industry have been around a while and have seen this same story play out over and over again. We can see the writing on the wall and they've destroyed the trust of their community so, a long winded blog post defending their decision, arguing that they are within their rights to do it is largely irrelevant at this point. They've lost the narrative and the industry (us) will respond by gradually finding ways either away from or around Red Hat and associated projects. Soon, the only people left using it will be the same people who use other irrelevant and dated software, government.
