Tim Cook Says He's Gay: Zuckerberg, Nadella, Pichai, Clinton, and Other Reactions

Apple CEO Tim Cook wrote an emotional letter in Bloomberg Businessweek on Thursday, announcing publicly that he's gay.

"While I have never denied my sexuality, I haven't publicly acknowledged it either, until now," Cook wrote. "So let me be clear: I'm proud to be gay, and I consider being gay among the greatest gifts God has given me."

The tech industry had largely positive reactions, with the likes of Microsoft CEO Satya Nadella and Android chief Sundar Pichai expressing their thoughts of Twitter. Facebook CEO Mark Zuckerberg, of course, shared his thoughts on the world's most popular social networking sites. Some of Cook's colleagues also took to Twitter to express their support.
