The posting of the open letter on centos.org was an extreme measure. The content of the letter illustrated a profound crisis and most commentators found it quite shocking.
Compared with how the mainstream IT market flies off their handles whenever something sensational happens at Apple or Microsoft, Corbet's reporting on this has been factual and sober.
Seriously guys, the CentOS guys made a very tough call. The worst fallout was not here on LWN though - not by any measure.
Also, CentOS users have to acknowledge the moral reality that they are enjoying what others are essentially sponsoring (RHEL subscribers). This is their GPL-given right, but the defensiveness in some of the comments here are a bit perplexing when one considers this fact.
