I'm sure there are a bunch in the same boat. I owned Oculus' DK1 and DK2, but when I thought through what FB owning Oculus meant, I cancelled my original Rift preorder and bought a Vive instead.
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.
I know what you mean. I have no problem owning and using a Facebook account, but that's my choice and I choose what to share. I don't know about you but when I first heard that Facebook had acquired Oculus my first thought was something along the lines of "Oh FFS".
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.
