Well they did lay off a ton of developers in exchange for LLMs. I bet the LLMs are capable of writing secure code anyway. So it's not even on my radar. But now knowing they also cut implementation of MTE means it's even less secure. So either they are refusing to admit their mistakes, or they are bowing to the governments wanting a more hackable device, or both.

Google was being hostile towards open source anyway. So probably good that GrapheneOS skips this one. Maybe even more to a different line of devices that's is not moving in such a proprietary direction. The last few Pixels aren't even much of an upgrade and progressively keep falling behind on a lot of hardware, but the price keeps going up. They just aren't what they used to be, a tech showcase for other companies to be inspired by. So, I'd actually be happy if GrapheneOS moved to another line, though I don't know which would be ideal that actually allows unlocking and locking the boot loader without voiding warranty or actively killing the hardware out of spite but still has high end hardware.
