It's a decision of conscience. Do you:
- get a product that respects you and will be supported by Valve like all their hardware (the ancient Steam Link still works fine!) at a higher price or
- get a product that spies on you from all angles and sells your data to everyone who wants it, even the police, at a lower price point, while it might be become legacy hardware at the drop of the hat?
I know where i will be spending my cash.
Edit: one of the reviewers of the comparison between the Quest 3 and the Frame at GN started getting advertisements on his private phone for VR stuff after working with the Quest. That's the level of privacy the Quest offers you: none.
