With the recent announcement of Motorola partnering with GrapheneOS, I got curious about installing a custom rom like LineageOS or/e/OS on my Moto G Power (vegas) because I've been meaning to degoogle for a while now. As far as I can tell, Motorola has all the keys to be a primary development target: OEM supported boot unlocking, cheap devices, accessible hardware, etc. Why have their devices largely been ignored by custom ROM developers?
