Facebook had a rough 2018. The year included a #DeleteFacebook trend after a number of the company’s high-profile scandals were brought to light. Those include the promotion of propaganda and fake news by Russian trolls and the alleged selling off of user data and private information. And it wasn’t just the common profile owner who paid attention; many prominent tech leaders and famous users took note, too.

Here are some of the biggest stars that are no longer “friends” with Mark Zuckerberg, despite his many public apologies.

Actor Will Ferrell said he was appalled at Facebook’s response to the Cambridge Analytica scandal.

“I can no longer, in good conscience, use the services of a company that allowed the spread of propaganda and directly aimed it at those most vulnerable,” he said. “I love my fans and hope to further interact with them through my comedy via the mediums of film and television.”

Playboy

The iconic adult magazine said in March that it would suspend all its Facebook activity, citing privacy concerns and sexual repression.

“For years, it has been difficult for Playboy to express our values on Facebook due to its strict content and policy guideline,” the mag said in a statement. “Playboy has always stood for personal freedom and the celebration of sex. Today we take another step in that ongoing fight.”
