On the one hand, I completely understand the frustration. We paid for a piece of hardware and the notion of requiring an account to operate it seems like a breach of that contract.
On the other hand, I don’t really care. I already have an Nvidia Experience account and I’m signed into it.
The truth is, this is how everything will be. The mighty user record is a powerful thing. Being able to associate product usage with a person is something that is extremely valuable to companies. We’ve seen this in video games (even those that are off line), peripherals like with Razer Synapse, and much more.
This is something that isn’t going away.
Yes, they do want to send you a newsletter and continuously market to you but there will be the ability to opt out (that is the law).
Also, building on @teh_ninjaneer’s suggestion of a dummy account, you can add
+anything to a gmail address and have it return to your inbox. For example, you can do
email@example.com and then simply create a filter that automatically archives any mail sent to that address.
This method keeps your mail in one place but also allows you to track who is sharing your address and how it is being leaked or sold.
