I'm not trying to be a jerk, I'm genuinely curious what you think could convince you. Perhaps you could get a job at Google and investigate the relevant code?
Opting out of that doesn't mean Google stops tracking you. Only some parts of its machinery stop. Even Google's own employees have no idea which parts collect which data.
One of the perks of working for us is a google no-ads subscription! could work?
If you try to take it literally it blows up immediately. Who aren't we collecting data about? We can't very well have data like login credentials for a user we don't collect data about, so...
If my arithmetic is right, 1.5bn searches would increase DDG's number of searches 15 fold. It would seem only Bing is potentially capable of putting in a bid similar to Google's.
Sounds like Google is getting a pretty good deal.
AFAIK on iOS you cannot distribute an alternative browser (as in UI, network engine and rendering engine) --- you can only distribute what is essentially a skin over the default browser, Safari.
15b USD/year / 500 m users = 30 USD/user/year
3 searches/user/day = 1000 searches/user/year
30 USD/user/year / 1000 searches/user/year = 0.03 USD/search
AFAIK, 0.03 USD per search (or impression) is in the right ballpark for advertising.

Data used (retrieved from Google) 446m Safari users. An average user searches on Google 3 - 4 times per day.
