Another arm of Alphabet, the holding company for Google and a collection of other businesses, has gone away. 

Within the past month, Alphabet quietly moved Jigsaw, a technology incubator that creates tools to curb online misinformation, harassment and other issues, under Google management, The Information has learned. It previously operated as a stand-alone unit of Alphabet. Jigsaw is the third Alphabet subsidiary over the past two years to be shifted to Google, which before that swallowed up cybersecurity company Chronicle as well as Nest, a maker of smart home devices. Those changes, along with the departures of Google co-founders Larry Page and Sergey Brin—the architects of the Alphabet organization—have prompted speculation about the future of the holding company.
