Only the provider of that service can provide that, and not even completely.

Third parties promising it would still be at the whim of the original provider. If they shut down the service, what would that third party do to fulfill their promise to you?

What we need is open, documented protocols for internet-connected hardware and escrow for pure internet services, with a guarantee to open source if the original provider shuts down their servers.

The latter will be difficult to enforce. The service provider could, instead of shutting down the service, just raise prices to something above absurd, and then shut down once all customers are gone.
