I think the important bit is that it's relatively hard to argue that "how to scale up message passing infrastructure and process metadata like hashtags" is a Twitter trade secret rather than a general tech skillset useful across FAANG companies. I suspect Meta's implementation will be quite different from Twitter's under the hood, and rely quite a lot on Meta tech platforms. If Meta was incubating a rocket ship division, it might be a little bit easier to demonstrate that former SpaceX employees were making non-obvious design choices based on SpaceX research and undisclosed features of SpaceX tech Probably won't help that a lot of the more Twitter-specific knowledge around content recommendations and warning algorithms and scaling up moderation processes is stuff Elon's spent his time trashing Twitter's original implementations of anyway...
