Steve Wozniak, the co-founder of Apple said that he is leaving Facebook, amid the concerns regarding the security safeguards about the personal information that the users share with the social media giant.

On Sunday, Wozniak wrote in a Facebook post that he is currently in the process of leaving Facebook and the social media has only brought him more negatives than positives. He further added that Apple has more secure ways to share things about oneself and that he could still deal with the old school email and text messages. In the latter part of the day, the “Woz” Facebook profile from which he had posted the message of departure was no longer accessible and it appeared to have been deleted. An effort to contact Wozniak through his cellphone was found unsuccessful.

The announcement of the tech pioneer marks the recent development in the back-and-forth corporate sniping by the tech leaders as Facebook copes with a scandal over the potential misuse of the user information by political targeting firm Cambridge Analytica. Last week, in an update, Facebook estimated as many as 87 million people in the U.S. could have had their information shared improperly.

Tim Cook, the CEO of Apple began the unusual public criticism late in the month of March. At the time of a joint interview with MSNBC and Recode, he was questioned as to what he would do regarding the crisis if he were in the position of the Facebook CEO Mark Zuckerberg.

Tim Cook replied to the question saying that he would not be in the situation.

He further added the Apple reviews apps in order to confirm that each one meets the privacy standards that his company has required for the users.

Cook said that “We do not subscribe to the view that you have to let everybody in that wants to, or if you don’t, you don’t believe in free speech.” He added that they do not believe that.

Cook even questioned the practice of the social media platforms monetizing the personal information of their users.

Facebook founder Zuckerberg hit back in a subsequent interview with Vox by saying that the comments of Tim Cook were “extremely glib.”

Zuckerberg said that if one wants to build a service which is not just serving the rich people, then he needs to have something that the people could afford.

Zuckerberg, championing the business model of his own company said that at Facebook, they are squarely in the camp of the companies that work hard to charge them less and provide a free service that everyone could use. He further said that he does not think at all that it means that they do not care about the people.

Zuckerberg has been scheduled to testify before congressional committees this week in Washington regarding the Cambridge Analytica episode and the response of Facebook.

The recent comments of Wozniak are not the first time that he has thrown shade at the social media giants. When talking at an international business conference last year in Montreal, Wozniak said that he generally tries to “avoid Facebook and Google.”

As reported, he cited the  use of the widescale data-collecting operations of the companies that are used to assist in sharpening ad targeting of the social media platform’s users.
