Tesla and SpaceX CEO Elon Musk acquired Twitter on Oct. 27. Since then, several celebrities have vowed to leave the site, citing concerns over Musk's new policies and leadership.

Gigi Hadid said she will be leaving the platform in an Instagram story on Saturday. The runway model wrote, "For a long time, but especially with its new leadership, it's becoming more and more of a cesspool of hate & bigotry." She continued, "and it's not a place I want to be a part of." "I can't say it's a safe place for anyone, nor a social platform that will do more good than harm."

Hadid's account is no longer active.

"Grey's Anatomy" and "Scandal" writer Shonda Rhimes said in an Oct. 29 tweet, "Not hanging around for whatever Elon has planned. Bye." Rhimes' account, which hosts 1.9 million followers, is still online as of Tuesday.

A day later singer-songwriter Sara Bareilles wrote on Twitter, "Welp. It's been fun Twitter. I'm out. See you on the other platforms, peeps. Sorry, this one's just not for me."

Grammy-winning artist Toni Braxton has also decided to leave the platform. She announced her departure on Oct. 28.

"I'm shocked and appalled at some of the 'free speech' I've seen on this platform since its acquisition. Hate speech under the veil of 'free speech' is unacceptable; therefore I am choosing to stay off Twitter as it is no longer a safe space for myself, my sons and other POC," Braxton said.

Whoopi Goldberg shared her reason for leaving the social media site on the Monday broadcast of "The View."

"I'm getting off," Goldberg said. "I just feel like it's so messy, and I'm tired of having had certain types of attitudes blocked, and now they're back. I'm going to get out, and if it settles down and I feel more comfortable, maybe I'll come back."

"This is Us" actor Ken Olin announced his departure a day after Musk acquired the platform. "Hey all -I'm out of here. No judgment. Let's keep the faith. Let's protect our democracy. Let's try to be kinder. Let's try to save the planet. Let's try to be more generous. Let's look to find peace in the world," Olin posted

"Lost Boys" actor Alex Winter also left the platform. He has apparently opted to join the social media website Mastodon, according to his bio which now reads, "Left here for here: https://mastodon.social/@alexwinter"

Other notable celebrity departures include screenwriter Brian Koppelman, retired WWE star Mick Foley, American actor Tea Leoni, British actress Marina Sirtis and comic book artist Bill Morrison.

While some celebrities' accounts are still active – including Bareilles, Braxton, Koppelman, and Olin – others have been deactivated following their announcements. The accounts of Goldberg, Sirtis, Leoni, Foley and Morrison are no longer online.

Director Rob Reiner urged followers to stay on the site in an Oct. 31 tweet.

"Just hours after taking control of this platform, its owner spread crackpot conspiracy theories about the attempted murder of Speaker Pelosi," Reiner posted. "Now is not the time to leave. Now is the time to fight for our Democracy. Vote blue. Hold the Congress. Then explore options."

Journalist Kara Swisher and "Star Trek" actor George Takei have also said they will remain on the platform despite the new leadership.
