Google's basic problem: search ads are incredibly profitable when you're #1. But they've saturated that market. Nothing else they do with their excess cash can match those returns. If they do something less profitable, the stock price goes down.
Hence Alphabet's search for a "moonshot". But what management meant by "moonshot" was another high volume product with a huge return on investment. That's probably not going to happen in the home appliance space, which is price-sensitive and competitive.
