Eich is a different story; for a modern tech company with a presence in SF, which is super-pro-LGBT. Also I see mozilla more as a family than a company(I'm sure it's due to branding/marketing) and having a person who +++donated funds+++ to prop8 as the CEO was a very awkward concept for me to accept. It's one thing to believe different things than I do, it's another thing altogether to ///donate funds/// to prevent something that really does him no harm yet inconveniences/saddens others. To me, that's an ethically corrupt action. Then he becomes the CEO of a company that is soaked in a culture of leftwing pro-LGBT. It's the donation that crosses the line for me.
Furthermore, it makes me wonder if he'd use his legally-obtained funds as Moz-CEO to do similar, more significant, donations in the future to other laws that would conflict with the Moz culture.
I guess you have to decide when opinion is just that, or something more harmful. A KKK member shouldn't be leader of the BlackGirlsCode effort and Eich shouldn't be the head of Mozilla. Of course, this analogy shows that I think of Mozilla as a very open-minded, liberal, pro-LGBT promoter rather than just a company that makes software. I can't convince anyone to see mozilla the way I do, but somehow they've put that spell on me... and clearly on enough people to cause this whole ordeal and resulting fallout.
