It used to be possible to buy a Quest 2 without the requirement of a Facebook account, but that freedom came at a premium cost.
They announced that they're dropping that requirement.
And the alternative is that you sign up for a Meta account so your info will just be shared anyway. It was a while ago they made that announcement and it hasn’t happened. I was going to get the Quest 2 but I came to the realization I don’t want to support that company so went with the Valve Index. Sure it doesn’t have wireless but I’m not going to take it anywhere anyway.
