I put this in the same category as that snooping device insurance companies want people to install in their cars (tracks speed, breaking, etc). It&#x27;s optional till it&#x27;s not.<p>To put it another way, it&#x27;s only optional till its prohibitively expensive to maintain your privacy.<p>I think both of these should be banned at the Federal level before they become too pervasive. The slope is too slippery.
