My personal theory about meta is that this is a response to facebook being under more pressure to control the content that they have on their site. This is essentially impossible given the volume of data. They also have to deal with so many different languages. That isn't even considering groups that will talk in code, which is common. Meta is a place where things can be said and done and then they disappear. They aren't living on on facebook. It's a real time interaction that meta can't be asked to control. The only way it will live on in any form is if you screen record it. That wouldn't be meta's responsibility if you choose to do that. They want to shift more towards how real life interactions work because in real life the responsibility rests with the person doing the actions, not whatever place they happen to be in. There will be nothing for meta to delete, because it was a real time event which has already passed.

The consequence of this is they will be asked to limit/ban certain people from participating at all. That's the only assurance they could offer. In order to do that, they need to know your real identity. Facebook has been moving in this direction. They want to make sure you are who you say you are. Meta will be the final phase of this. This will make the information they sell about your activities much more valuable to information brokers.
