@mysk@mastodon.social Reply from @wabetainfo@mastodon.social : WhatsApp would need to move its entire database into http://group.com.facebook.family in order for other FOA to access it, and that is not the case. If only they did, some users would notice it, especially people like you. The database remains in WhatsApp's dedicated container. WhatsApp only moves the database to the Business container if the user chooses to switch their account to a business profile. Reply from @mysk@mastodon.social : They don’t need to move the database. They could add “group. net. whatsapp. WhatsApp. shared” group container entitlement to Facebook or Instagram apps. So it’s really just a policy decision that can change at any point by checking one box in Xcode rather than there being any technical limitations

Reply from @wabetainfo@mastodon.social : Again, if they were actually doing something like that, people like you would notice it and make it widely known, just as you did originally. Reply from @mysk@mastodon.social : Sure, and you’ll hear about it from us when they do 😬 The facts are: 1) WhatsApp, FaceBook, and Instagram have a common group container that is used to share data between them locally on device (we won’t speculate as to what is being shared) 2) Adding WhatsApp group container entitlement to other Meta app, where it stores the chat database in plaintext, would be a trivial technical change on Meta’s part. It would really go a long way if WhatsApp starts encrypting the chat database at rest as well. I think that’s all we can say right now Reply from @wabetainfo@mastodon.social : Encrypting the database certainly wouldn't be a bad thing either way 👍🏻 we will see how things evolve in the future.
