It’s just the website presents the game in series of very general and catchy glimpses. They are not there to give detailed idea of how game-play looks like or how particular features are implemented. “Travel to different worlds”, “collaborate in citizen-driven economy” etc. are hardly phrases promising anything in detail. And all sections there are written this way - in an attractive advertising style. They are hardly lies or set-in-stone promises.
The part about private worlds is a vague statement about private worlds in general (and they are called “personal” there, without going into actual types of them). Yes, this part could be re-written to be 0% misleading, but is it really misleading as much, especially if combined with the more important details given long time ago (as long ago as 2015) across many posts?
