Yes, I'm aware, I just ruled out all possible "Huaweis" and cheap Chinese stuff. While it's perfectly ok for the device to be assembled in China, you can't realisticly trust any company based there to meet strong security requirements. GOS team knows it, and if the choice is between a Pixel and a noname OEM, the choice will be clear.
Personally I will switch to the latest unlockable Pixel after the Goog gang decides to lock them, if that happens. So in the worst case scenario we have until end of 2032 to figure out alternatives.
