Apple, Google oppose gay marriage ban, while Yahoo stays silentGoogle crossdresser-in-chief Sergey Brin got his company, after contentious internal debate, to express opposition to Proposition 8, a California ballot initiative which would ban the same-sex marriages rendered legal earlier this year by the state's Supreme Court. Now Apple, too, has expressed its corporate views, donating $100,000 to the No on Prop 8 campaign. Who hasn't weighed in? Yahoo.We hear that CEO Jerry Yang wrote a long, rambling, presumably uncapitalized email to the troops explaining why the company, which is otherwise outspoken on gay rights, is not taking sides on the issue. Gay employees at Yahoo are purple with rage. Will someone forward us the memo? We'd love to read Yang's explanation of why, once again, he can't make a decision one way or another. (Disclosure: I got married to my husband last month, and recently held a fundraiser in opposition to Proposition 8.)
