nah. grapheneos requires open source drivers and immediate security updates from the oems as well as an unlockable bootloader. pixel just happens to be the only one who fits the bill for all of those. as an example, the Samsung I had before my pixel wouldn't get security updates for months after an Android release which was really annoying. Motorola will soon comply with these standards too, but they have their own line of flock camera alternatives so I won't be touching their products with a 10 foot pole.
