When talking about the everything app, while Elon might have coined the term, Zuckerberg is the one that seems to be implementing it more. You mentioned moving from Insta to X and using a different login, but there is Threads that uses the same insta login. Of course it isn't as popular Twitter, but the logic is there. Facebook show this everything app even more. Apart from the social media features that people already know, it has a marketplace, groups/communities like reddit, and games. For its video, it has a lot of options. There is the regular video upload, it has streaming, it has shorts, and it even has the snapchat video that disappears after a day. I know people are divided about facebook, but their continued release of updates and features helps them stay relevant.
