Damn, it may be time for me to move back to Android. Do Pixels require the updates to be sent by your carrier, or do they allow direct download?

unlocked, carrier-agnostic phones are the way to go.
With the Pixel updates, at least, the updates come through Google but the carrier (at least TMO) can prevent this from happening even if the phone is unrestricted.
