To be fair, the Mozilla thing was much more the "Are you now, or have you ever supported a political issue we don't agree with?" in nature. I'm not saying I agree with it, but that's the same type of question...
Eich was in a much wobblier position from the beginning, with board members resigning over his appointment, public denials about that, and eventual confirmation. That alone might have doomed him and the rest is noise.
John Lilly publicly confirmed he resigned rather than appoint Eich, without elaboration. I did not say the board resignations had to do with Eich's material support for Prop 8. WSJ stated all three resigned because of Eich's appointment, and none contradicted that report.
