Shared containers are also restricted by publisher – you can't share data with another publisher using them.
I believe the other container you're talking about is the keychain. You can store small amounts of data in there (typically secure auth info) and it will persist even after app deletion. This is hardware encrypted by the Secure Enclave and can't be shared between publishers.
Apple have shown that they are willing to remove big social media apps from the App Store just a few weeks ago, with Tumblr.
Also, collecting information for use in WhatsApp and using it for a different purpose in Facebook is a DPA and GDPR violation:
