It's a very good point that companies will (eventually) look to maximize revenue and thus even companies that start out with grand ideas of being "different" succumb to that pressure. A strong countervailing force (in some markets) is competition. If Google had more competition (both in terms of a independent search service and access to be the default search option in browsers) they might have to start caring more about the search experience and privacy.
