I agree with this, but I'd add that if you have already trusted Amazon enough to purchase and run 24/7 with full access to your home network their remotely controlled and configured internet microphone, drawing the line at this feature seems a little odd to me. If you own an Echo device and used it prior to this feature you had already granted a large degree (relative to this feature) of trust to Amazon anyway. It reminds me a little of people who swear they will never use an Echo device due to concerns about eavesdropping but happily carry an internet microphone equiped smartphone everywhere.
