Breaking those parts away from google absolutely wouldn’t destroy them, over the years I’ve been so surprised from googlers at most levels explaining how much money they make from all their different services. While advertising is absolutely a big one, it’s by no means the only one, and if i understand the situation correctly, the more advertising options that are actually viable for companies will not even kill their advertising business. But big business real doesn’t like competition.

Everyone related to the company, from shareholders down to the lowest on the totem pole are incentivized in some way to show quarterly growth, so they will do so at all costs.
