How Silicon Valley leaders, from Elon Musk to Tim Cook, are responding to the George Floyd protests

Google will match any employee contribution up to $10,000, Pichai said in the memo, which was obtained by Business Insider.

Google also added a black ribbon to its homepage to show support for racial equality. "For those feeling grief, anger, sadness & fear, you are not alone," Pichai wrote on Twitter.

In a post on Facebook, Zuckerberg praised Darnella Frazier, who posted the video of Floyd's death, saying that as hard as it was to watch, "we all needed to see that."

Zuckerberg said Facebook would donate $10 million to racial justice groups recommended by employees and the company's "civil rights advisors." He also detailed the Chan Zuckerberg Initiative's work in criminal justice reform, which he said has invested somewhere in the neighborhood of $40 million over the last several years.

"The pain of the last week reminds us how far our country has to go to give every person the freedom to live with dignity and peace. It reminds us yet again that the violence Black people in America live with today is part of a long history of racism and injustice," Zuckerberg wrote. "We stand with the Black community — and all those working towards justice in honor of George Floyd, Breonna Taylor, Ahmaud Arbery and far too many others whose names will not be forgotten."

Musk responded to a video on Twitter, saying that it's "definitely not right" that the other police officers present when Floyd died weren't charged.

In a memo to employees, Cook wrote that we must stand up for one another in the aftermath of Floyd's death and in light of "a much longer history of racism," Bloomberg reported.

"That painful past is still present today — not only in the form of violence, but in the everyday experience of deeply rooted discrimination," Cook wrote. "We see it in our criminal justice system, in the disproportionate toll of disease on Black and Brown communities, in the inequalities in neighborhood services and the educations our children receive. While our laws have changed, the reality is that their protections are still not universally applied."

Cook said Apple would make donations to the Equal Justice Initiative, along with several other groups, and would be matching all employee donations two-for-one in the month of June.

"George Floyd's death is shocking and tragic proof that we must aim far higher than a 'normal' future, and build one that lives up to the highest ideals of equality and justice," Cook wrote.

"We stand against racism. We stand against bigotry. We stand for justice," Sandberg wrote.
