For exceedingly small values of "good".
Do you have anything more valuable than your time? If you're confused about the question, imagine you only have two minutes to live, and how much of that time do you want to waste in your confused state.
Now consider how much of your time the google would like to fill with ads. The answer may surprise you: ALL of it. Of course that isn't possible, but we have to let the google dream, don't we?
There was a time some years ago when I believed the motto "Don't be evil." Later on I thought the motto could be fixed with a bit of tinkering, something along the lines of fixing their other motto to be something like "Making all of the world's information available while helping you protect your privacy." These days, I think the google has a new motto:
"All your attention are belong to the google!"
At first I didn't blame the google so much as the rules of the American business game. Then I learned that the google had become the largest tech lobbyist bribing the pols. Very few companies that I actually want to deal with these days. Just picking the least bad option--like the pols (on those rare occasions when the pols didn't pick their voters first).
