The situation with the Nancy Guthrie disappearance and Nest camera footage is related, and interesting. It seems that she had a Nest doorbell camera, but didn't pay for the subscription plan ($100/yr?). As a result, the camera records short snippets but doesn't save them to the cloud in a user-accessible way.

After a week, Google finally hunted down/coughed up the footage. I imagine there were some people within Google who realized that if they provided the footage immediately, then it could discourage people from paying for the subscription.

Of course, they must also realize that by not providing the footage sooner, they may have allowed the perp to get away, or the victim to be killed.
