Has any other company been in a position where they'd have to offer refunds though? The combination of a hardware device that relies entirely on an external service and requires "purchases" rather than rentals, and said service being discontinued after only three years and the company in question still being solvent seems like it'd be a black swan.
Google is refunding everything, not just hardware.
Contrast this to Amazon for instance, where movies/tv shows you have bought just disappear from your account when Amazon loses the license to serve them.
