Google is notorious for suddenly discontinuing apps and services, even those in wide use. That practice actually applies even to hardware products, much to the disappointment of many customers. The casualty in the latter segment is its Nest-branded smart home security system which suddenly became no longer available last week. To assure customers it isn't pulling the plug, Google now publicly commits to continue supporting the Nest Secure system. It isn't, however, saying anything about updates and new features.
