What draws attention is Brendan Eich's political support - Eich donated to the anti-marriage equality Prop. 8 campaign in California. In plain words: anti-gay supporter.
Mozilla’s head of education, Christie Koehler, who is gay wrote on her blog: “Like a lot of people, I was disappointed when I found out that Brendan had donated to the anti-marriage equality Prop. 8 campaign in California. It’s hard for me to think of a scenario where someone could donate to that campaign without feeling that queer folks are less deserving of basic rights.”
To be fair, Mozilla has nothing to do with equal rights issue. However, due to its unique company or organisation which "promote openness, innovation and opportunity on the Web" (Mozilla's mission), many Mozillians are themselves associated with and advocate for human rights, animal rights, marriage equality, racial equality, etc... (yes, you get the picture). There are reports of Mozilla employees telling Eich to step down (Ars Technica).
It has been a long time since we last saw "best viewed with (certain browser)" or please change your browser to continue use certain site thing. Recently, a well known dating website (OkCupid) encourages users to ditch Firefox and its anti-gay CEO (news.com.au).
Brendan Eich has since posted a response on his own blog expressing sorrow “having caused any pain” and reinforced how his views would not affect work at the company:
“I am committed to ensuring that Mozilla is, and will remain, a place that includes and supports everyone, regardless of sexual orientation, gender identity, age, race, ethnicity, economic status, or religion.”
