No on Prop 8
Apple is publicly opposing Proposition 8 and making a donation of $100,000 to the No on 8 campaign. Apple was among the first California companies to offer equal rights and benefits to our employees’ same-sex partners, and we strongly believe that a person’s fundamental rights — including the right to marry — should not be affected by their sexual orientation. Apple views this as a civil rights issue, rather than just a political issue, and is therefore speaking out publicly against Proposition 8.

Hier noch was zur Proposition 8 aus Wikipedia:
Proposition 8 is an initiative measure on the 2008 California General Election ballot titled Eliminates Right of Same-Sex Couples to Marry. If passed, the proposition would “change the California Constitution to eliminate the right of same-sex couples to marry in California.” A new section would be added stating “only marriage between a man and a woman is valid or recognized in California.”

The measure was originally submitted for the ballot by petitioners with the title “California Marriage Protection Act.” The title and summary were revised by Attorney General Jerry Brown to more “accurately reflect the measure.” The Superior Court of California ruled in favor of these changes, stating, “The title and summary is not false or misleading because it states that Proposition 8 would ‘eliminate the right of same-sex couples to marry’ in California. The California Supreme Court unequivocally held that same-sex couples have a constitutional right to marry under the California Constitution.”
