Tech leaders in Silicon Valley are speaking out about the U.S. Supreme Court ruling that says same-sex marriage is "the law of the land."One of the first reactions came from Tim Cook. The Apple CEO, who is gay, has long been a public champion of human rights.[seealso url="http://sale-online.click/2015/06/26/gay-marriage-ruling/"]In 2013, Cook wrote an op-ed for The Wall Street Journal about LGBT workers' rights. And last July, he marched with other Apple employees at San Francisco's Pride march.On Friday, Cook's tweets were eloquent and to the point:[twitterEmbed url="https://twitter.com/tim_cook/status/614449483292618752"]He also managed to reference Apple's most famous ad campaign, "Think Different."[twitterEmbed url="https://twitter.com/tim_cook/status/614449593627979776"]The Supreme Court ruled on Friday that bans on same-sex marriage are unconstitutional, which makes it legal in all 50 states.In a statement, Apple told us:"We applaud the Supreme Court and everyone who worked so hard in the years leading up to today's historic decision. This is a momentous step forward for equality and fundamental human rights in the United States. We could not be happier for our employees, customers and people all over America who now have the right to marry the one they love."[wp_scm_comment]
