Why are there a bunch of Horizons worlds showing in my library?

Since I am here reading this it means like everyone else here I was searching for a way to get rid of it.

I have no interest in Horizon Worlds or VR Chat. I am also tired of getting notification of "check out this World"

I fear commercials will be coming. First when you fire up your Quest, then before and after playing a game, and finally during the game. And don't forget that No Ads subscription they will start. Maybe by then Pico or another headset will be available here and we can leave this Matrix behind for the kiddies.
