Restricting screenshots is laughable security. If you can read a message then you can take a picture with a second device, there isn’t any software that can stop that.
Preventing screenshots can stop accidents and make someone think twice about it, and disappearing messages prevents returning later and looking them up, but that’s it.

Well yes obviously nobody can prevent the recipient from taking a picture of the screen with a second device or writing down manually what the message said.
No system is foolproof, but those features are definitely miles ahead of anything meta provides, since they dont actually want those chats to be encrypted. They want that data, it is their business model.
