Opinions about the GrapheneOS maintainer aside, there are real reasons why device support has been limited to Pixels (note recently announced intentions to support Motorola devices). As long as you understand what you will/won’t be getting with this fork (can it be decrypted BFU/AFU with a cellebrite device?) in comparison to GrapheneOS, then power to you. I recently switched to GOS after years on LineageOS with microG. I do miss my OnePlus hardware, and Graphene took some getting used to. But I do feel comfortable that I’m running the most secure phone now.
