I have successfully argued this for at least a certain class of devices. Namely, it practically can't happen _for small devices_. e.g., a TV remote with a voice feature activated by a button simply won't have enough _power_ to constantly be listening, uploading, or processing.
Harder to convince folks that _nothing_ does this, but takes an edge off their more paranoid tendencies.
