How does this actually help with owning your own data and repatriating it?
The integrations that are installed on the end devices (phone) sync all that private data into the cloud platform regardless of the backend server. State is shared.
Google Information Services, and Apple's backend's unpublicized equivalent both process and store that related data, regardless of the phone you choose to use or the options you choose on that phone. There is a reason gigabytes get sent up to the cloud every evening, and its all encrypted.
Until you remove the implants on your phone you won't be able to receive any benefit from repatriating the data. That requires jailbreaking, or installing a new OS (something like Graphene), which is model specific due to compatibility issues.
