Meta is not letting people out of it’s walled garden. Meta will use our free world as a safari, selling tickets to their users so they can watch and interact with us, monetizing our content, while still being guided (since they can decide what content they see, and how do they see it) and watched by Meta (because they know every move of their users at any other instance) at every step they take outside of it’s walls - because they are still from their instance. It will use those safari rides as an excuse to collect as much data about what we do here, unknowing to the people they sent here. In addition to that, you will get 3 billion of people who will just leave trash everywhere they go on our vast open plains, and Meta will eventually just use that as an example of how we can’t handle cleaning our space, and use it as a reason why people should go live within their walls - because the walls will still be there, and every step you take within them, even if you’re only visiting from outside, will be heavily monitored.
