It had been reported in Distrowatch.com that "numerous developers quitting the project" and a lot of pushing and shoving on the mailing list and forum.
Whatever started the "internal issues" albeit avoidable had happened and we'll all have to get on with it.
I would have nothing short of wishes of luck and successes to the result of this split, Unity Linux and wish that all this back-stabbing and flame would cease and desist.
I will stick with PCLinuxOS for nothing more than Texstar. Although I don't know him personally, and I've never met him face-to-face, I believe that he is a good person. Sure he blew a fuse ONCE but understand that his health is in the balance and he had a shuffle of priorities because of this. Even if PCLinuxOS is not in his top priorities, he knows that it is his legacy. And it will nevertheless be a good legacy because the truth will eventually come out and Texstar did his best to handle the situation - both in the development and community board.
