[...] Even digital companies that have grown too wealthy and unwieldy, such as Facebook and Google, now innovate through acquisition of startups—for which they pay a king’s ransom. Google has turned itself into a holding company, Alphabet, as if to better reflect its new role as the purchaser of other firms’ ideas.
