Still, Facebook users will no doubt be pleased to - eventually - be able to remove messages they change their minds about.
Unlike Zuckerberg and some other Facebook officials, Facebook users do not have the ability to delete their own messages from their own inbox, much less erasing the ones they already sent to other people. "We did so in full compliance with our legal obligations to preserve messages".
Before there was Facebook in America, there was Facesmash at Harvard and Mark Zuckerberg was behind both of them. More often than not, his apologies have followed revelations about how little regard the social media site has for user views and privacy interests.
There's no indication that Facebook actually plans to introduce such an option, but Sandberg's admission makes explicit that Facebook's revenue depends nearly entirely on monitoring its users' taste and behavior.
According to a report by Engadget, users have had received messages from CEO Zuckerberg previously, as early as 2010. They're people who use Facebook, so are investors. Zuckerberg also expressed his support for the Honest Ads Act bill now working its way through the Senate-despite Facebook having previously lobbied against it.
A Facebook spokesperson told TechCrunch, "We have discussed this feature several times. And people using our secret message feature in the encrypted version of Messenger have the ability to set a timer - and have their messages automatically deleted", a Facebook spokesperson claimed. This may take some time.
Cambridge Analytica tweeted on Wednesday, "When Facebook contacted us to let us know the data had been improperly obtained, we immediately deleted the raw data from our file server, and began the process of searching for and removing any of its derivatives in our system".
The Ministry of Communications and Information Technology says in a statement Friday it has asked the National Police to investigate possible violations of Indonesia's privacy law a day after Facebook announced that personal data of more than 1 million Indonesians might have been exposed by political consultant Cambridge Analytica.
Sandberg said Facebook has launched an investigation and audit to determine whether user information has been compromised by other firms. And until this feature is ready, we will no longer be deleting any executives' messages. Rather, these users are "a regime of one-sided, highly profitable surveillance, carried out on a scale that has made Facebook one of the largest companies in the world by market capitalization,"Tufekci wrote. Mark [Zuckerberg] is really sorry for that, and what we're doing now is taking really firm action".
