The point here is that Waymo requires either an Android account or an Apple account to log into their phone app. Lose that and you cannot take a Waymo. This may be worth a formal complaint to the California Public Utilities Commission, because Waymo is regulated as a common carrier.
California civil code section 2170:
"A common carrier must, if able to do so, accept and carry whatever is offered to him, at a reasonable time and place, of a kind that he undertakes or is accustomed to carry. A common carrier must not give preference in time, price, or otherwise, to one person over another."[1]
This is the core of what it is to be a common carrier. An airline can't require that you join their frequent flyer plan to fly.
