The guy is a sleaze-bag, who chose to attack an open source browser (with an important role for the future of the internet, and the work of thousands) through his business for the benefit of getting positive PR for his business.
I wonder if Brendan Eich had this mentality, how he'd spin it. "Oh, I apologize, I thought Prop 8 was about supporting the gays, damn. I didn't do my research!".
But he doesn't have this mentality. So he instead chose to abandon the work of his life in order to preserve it, a rather painful action, as his spin-skills and spin-will were insufficient.
It basically means that those of us who are willing to...
1) Attack others for their political actions for PR reasons.
2) Engage in the same type of political actions.
3) Lie they were ignorant about it.
4) Say "sorry" without feeling any guilt.
... have a huge edge on those honest people who just say things as they are, without spinning things.
Damn, no wonder sociopaths are ruling the world, huh?
