Apple is celebrating Martin Luther King Jr. Day with a full-page photo and a quote on its homepage.

Tim Cook also tweeted another King quote:

Sadly and predictably, some Twitter users hijacked the message to reply with complaints about Apple slowing down older iPhones.

Martin Luther King Jr. Day is a federal holiday in the U.S. to mark the birthday of the famous civil rights leader. King advocated non-violent opposition to racial discrimination. He is best known for his ‘I Have a Dream’ speech delivered from the steps of the Lincoln Memorial in Washington, DC, to an audience of around 250,000 people. It has gone down in history as one of the most inspiring and impactful speeches of all time.

Slowing down older phones cannot buy loyalty; only ethical business practices can.

Er yuh, okay… now about my iPhone performance…

The holiday was signed into law in 1983 and first observed in 1986, but opposition in some states meant that it was only officially observed across the country from 2000.
