Zuckerberg outlined a multi-step response that Facebook plans to take to prevent this situation from recurring, and one feature Facebook will add is a new tool at the top of the News Feed which will let people see which apps they've used.
Any app used on the Facebook platform has access to a user's personal data, so the Facebook tool will let people see which apps have their info and it will offer up an easy way to revoke permissions.
This tool is already available through Facebook's privacy settings, but the company plans to make it more accessible to all users.
Back in 2014, Facebook implemented changes to reduce the amount of data apps had access to (the CA data was pre-2014), and Facebook says it will now investigate all apps that had access to large amounts of information before the platform change.
We will conduct a full audit of any app with suspicious activity. We will ban any developer from our platform that does not agree to a thorough audit. And if we find developers that misused personally identifiable information, we will ban them and tell everyone affected by those apps.Zuckerberg also says Facebook plans to remove developers' access to data if an app hasn't been used in three months, and the amount of data provided to an app when a user signs in will be further restricted to name, profile photo, and email address. Access to posts or other private data will require users to explicitly approve the action.
The Cambridge Analytica scandal has resulted in a massive "Delete Facebook" movement from users concerned over the data Facebook collects and how it's used, and Facebook stock has sharply declined this week.
Facebook users who are not satisfied with Zuckerberg's response can permanently delete a Facebook account by clicking this link. Before doing so, it's recommended Facebook users download an archive of their content so no photos are lost.
