> I have WhatsApp to talk to some family and I recently disabled allowing all contacts in iOS 18. WhatsApp now has a persistent notification at the top of messages to "Allow All Contacts".

If this is still possible, then Apple fucked up the implementation of this feature, as clearly there should be no way to differentiate not having bothered to fill out a ton of contacts and having limited access for an app to see your contacts; and since this is so obviously easy to do correctly, it frankly sounds actively malicious: there is a set -- probably a very small set -- of engineers and product managers who chose to build this incorrectly, in order to continue to maintain the status quo of the proxy war between Apple and Meta, to our detriment.
