The sheer fact that internet access exists for them indicates there's a use case. And it's obvious. Over the air updates are objectively a better user experience. Maybe even the best.

The problem isn't that the devices have internet access. It's that we don't have appropriate legislation governing protection of privacy that would keep this kind of snooping in check.
