Zuckerberg sees messaging as critical to the company's future, and by letting people send messages to WhatsApp and Instagram contacts from within Facebook, they will be kept on the platform for longer.
The Irish Data Protection Commission has called on Facebook to provide it with an "urgent briefing" on the proposals.
Doing so could put Facebook on a collision course with European Union officials, who have repeatedly blocked it from using personal data from WhatsApp users.
The three apps have, historically-speaking, targeted different audiences, had different uses, and different structures. This change will also allow users to message each other from any of the three apps without having to switch platform.
According to some ex Facebook security engineers and a third-party encryption expert, the plan could be a positive move in the direction of user privacy, especially if the end-to-end encryption happens.
Those documents revealed that Facebook encouraged developers to make in-app purchases without their parents permission, according to The Center for Public Integrity, which convinced U.S. District Court Judge Beth Labson Freeman to unseal the material. On disposal, the Whatsapp founders Brian Acton and Jan Koum, it was mentioned, you could have been against plans to weaken the encryption. So, this is good news for privacy but only if it is done properly. When Facebook acquired Instagram back in 2012, and later WhatsApp in 2014, Zuckerberg made assurances that the entities would continue to operate separately and enjoy autonomy from their parent company. For examples, for ads, they would build a single user profile from all of the apps. With this increased privacy issues, there is no requirement for real identity to use WhatsApp (unlike the main platform, i.e Facebook).
Each service would still exist is a standalone app, so users will not be forced to download another new app.
Unifying user data would be a big boost to Facebook's advertising business because it means it could really target potential clients for its advertisements.
It may be early days for Facebook's plan to integrate Messenger, WhatsApp, and Instagram, but one regulator already wants answers. It's unclear when the three chat apps will be unified.
What features will be available as part of cross-platform messaging?
This would mark the first time they've been able to communicate across the platforms.
