The problem is to achieve acceptable quality of service for an online cloud OS service with all the responsive UIs and expected reliability, everything has to be done locally-first either way, using approaches like CRDTs. And even more so for Google, because their level of service quality delivered over public internet is nowhere near acceptable for an OS and will never be. But, of course, they can still offer locally-first OS as a service, not giving users any control.
