How would money be involved?
It's not like GOS is in a position to force device manufacturers to open the bootloader and have strengthened hardware, let alone make phone prices accessible. The best they can do is kindly ask a manufacturer to do so and hope that they agree (which Motorola have technology-wise).
And if it's a money issue for people, then buying the newest pixel phone is still not cheap (~1k+). And most privacy advocates recommend buying the phone used and with cash so it's not associated with your bank details.
