Companies like Nike, Twitter and Citigroup have aligned themselves with the Black Lives Matter movement... Twitter, which spent much of last week battling President Trumpover the warnings and fact-checks it placed on several of his tweets, changed its profile image on the platform to black and added “#BlackLivesMatter” to its description... he advertising agency 72andSunny wrote on Instagram that “white people need to start carrying this burden” of combating racism. Reebok said in a message to “the black community” that it “stands in solidarity with you,” telling its social media followers: “We are not asking you to buy our shoes. We are asking you to walk in someone else’s.”

 ... WarnerMedia brands, including HBO, TBS and the newly introduced HBO Max, changed their Twitter names to #BlackLivesMatter and quoted the black novelist James Baldwin: “Neither love nor terror makes one blind: indifference makes one blind.”... The hashtag also appeared in posts from retailers like Nordstrom, the ice cream maker Ben & Jerry’s and media companies like TikTok. YouTube promised to spend $1 million on social justice initiatives, but it quickly faced criticism that its moderation effortsagainst racist content have historically been weak... “Your hypocrisy knows no bounds,” wrote Sleeping Giants, a media watchdog group, in a reply to YouTube that echoed a similar complaint against Twitter. “As a platform that has done its very best to avoid having to remove any videos from racists, white supremacists and hate mongers, you should be ashamed of even tweeting about this. Too little, too late.”
