Even if it were just the Quest: How is it reasonable to require an account to use a "stand alone computing device"? I have many stand alone computing devices in my home without the need for an account with their manufacturers.
I was already skeptical of my Oculus Rift when after buying it I learned I needed to create an account just to download drivers (WTF!) No other device on my computer requires an account to obtain drivers. I would love to hear the justification.
Take oculus Rift as an example. You own a game (on a different platform) which supports VR (including your device). You plug your Rift in, calibrate the sensors/room and start playing the game. You shouldn't even need internet connection.
For support requests, use the serial number, like everywhere else.
Consoles work offline just fine.
"We require you create an account so that we can protect your personal data."
The thing is: to sell me stuff, you don't need to know my name. You don't need to keep tabs on me. You may offer it, but I may decline. Plenty of mortar-and-bricks-stores work this way: there are loyalty cards for tracking, but customers who forego them do not have to register to make a purchase.
Point in fact: there are also internet shops that allow such options. Sure, they need a bit of data to send the parcel and the confirmation/invoice/etc. But that doesn't require everyone to create a username/password combination - and some internet shops blissfully do not require that. They get paid and ship the purchase to the address specified, and that's it.
In this case, it seems purchases could be tied to the Oculus device specified during the purchase. While I can certainly imagine benefits to tying purchases to a user account (e.g., ability to use on multiple Oculus devices), I don't see a reason to require logging in. Am I overlooking something?
If (when) the device fails, you would lose all of its associated software licenses and have to buy them again
