It's not really a requirement of a Pixel device. It just happens to be the case that Pixel devices currently are the only devices meeting the hardware requirements listed in the FAQ: https://grapheneos.org/faq#future-devices. The hardware requirements don't contain exoctic things but non-Google and non-Apple companies until now just fail to deliver on the security front. It's also not that GrapheneOS catered these requirements to fit to Google and Google only. They are actively working with an OEM partner since June 2025 to help them meet the hardeware requirements for a subset of their future devices. So they are even willing to assist companies to meet the requirements if they have the ambition to do so. The OEM is not yet disclosed, the launch of the device will be somewhere in 2027.
