I pre ordered one then realized the fb login requirement and cancelled it. Wonder how many are in the same boat.
More recently, my resolve against letting FB get their data proboscis into my life was weakening with the Quest 2 launch. Fortunately, they came up with that forceful reminder of why I made that decision in the first place.
In my opinion, if I pay money for a product I don't expect to have my privacy violated so I can be further monetised. The point of a Facebook account is I have made a deal that I will allow information about my use of the product to be used as payment for the product. That is not the case for something I have already paid for.
