It’s a bit of my suspicion mixed in with comments I have read that agree with this point. I don’t know if there is solid evidence though. Point is Graphene OS is software but that doesn’t affect the Tensor chipset. I know even with laptops you can install Linux but your privacy is still compromised by the hardware. Basically I don’t trust Google hardware. If you search “Pixel Tensor Privacy” you will find different places this is discussed.
I’m not exactly sure what the best option is to use. It very well may be a Pixel with GrapheneOS. Being the most private, doesn’t mean it’s private though. Just better than the rest.
