If you ask, the leaders in that area of Google will tell you something like "we're actually HELPING users because we're giving them targeted ads that are for the things they're looking for at the time they're looking for it, which only makes things for the user better." Then you show them a picture of YouTube ads or something and it transitions to "well, look, we gotta pay for this somehow, and at least's it's free, and isn't free information for all really great?"
