Some early employees of Alphabet's smart-home company Nest, including co-founder Tony Fadell, are frustrated by how the company's history has played out now that it has been rolled back into Google.

Google bought Nest for $3.2 billion in early 2014, less than two years before it blew up its corporate structure to form the holding company Alphabet. Under Alphabet, Nest became an independent company and was heralded as the model business in the "Other Bets" category, which also includes Alphabet's venture capital arms, its smart city project Sidewalk and other experimental businesses.
