Recently, media reports claimed that the personal data of more than 500 million Facebook users were available on a hacking forum. It was also revealed at the time that the personal details of Facebook founder Mark Zuckerberg were also included in the data.
The data was leaked to hackers in 2019 as a result of a security flaw, and now a security researcher, Dave Walker, claims that Mark Zuckerberg uses Facebook's proprietary WhatsApp anti-messaging app Signal. He made the claim using Mark Zuckerberg's phone number in the data and shared a screen post on Twitter.
In another turn of events, Mark Zuckerberg also respects his own privacy, by using a chat app that has end-to-end encryption and isn't owned by @facebook— Dave Walker (@Daviey) April 4, 2021

It is possible that the signal was used by the founder of Facebook so that they could check the opposing app. But it is also possible that Mark Zuckerberg used the anti-WhatsApp app because of its security. Needless to say, the protection of signal data is a top priority and security, features and other aspects have been designed with this in mind.
Dave Walker also said that Mark Zuckerberg's alleged account has been closed since April 5. He also hinted that Mark Zuckerberg was apparently not on the telegram, but that the messaging app provided the user with the facility that the user could not be traced by phone number.
On the other hand, according to this report, Signal has also satirized Mark Zuckerberg.

"As the May 15 deadline for accepting WhatsApp's Terms of Service approaches, Mark Zuckerberg has taken the lead in setting an example," the signal said in a tweet.
On the other hand, when contacted by the Android Authority, a Facebook representative refused to talk about it.
