Ugh - those omissions are not self-serving. The reality (which we all see) is that the dev team f*cking hated the game, probably gave up on quality, and everyone knows it. But saying so is an attack on the people Garriott screwed when he screwed up; the omissions are of other people's contributions to his faults, not his faults themselves.
The apology was _incredibly_ well-written: it highlights all of garriott's mistakes, in detail, and places the blame squarely on his own shoulders: he could say "EA is evil because they enforce business discipline," but instead said "they did their job as a business, and I didn't so mine as a creator."
If anything, this was probably _too_ self-blaming (we all know EA would just replace him if he didn't bow down, accomplishing nothing). But don't criticize him for failing to throw his team under the bus. Knowing very little, I'd love work for this guy, based on that apology alone.
