> Apple lost my trust with their maps. They were willing to push a bad product to their customers as a negotiating card against Google. I don't know the details but I assume it was about money. If I ran Apple, I wouldn't be comfortable displaying ads on an app that is 1. installed for all users by default 2. the user cannot uninstall. I am OK with a built-in app doing data collection for ads provided it only starts collecting said data after informed consent. However, displaying ads from Google's ad network would hurt me in at least two ways: 1. it ruins the default experience for the users (I think Google agrees that ads are bad for user experience or it wouldn't have things like YouTube Red or soon to be called YouTube Premium) 2. it ruins my relationship with advertisers who now have to go through Google to reach my customers. Google, I assume, is also unwilling to provide Google Maps free of charge without 1. contributing data back to make Google Maps better (and serve better, higher paying ads) 2. allowing Apple to serve as the sole ad exchange for Google Maps for iOS Once again, these are just my guesses. I know nothing about the industry. I thought it was strange that advertisers don't simply trust Google when it comes to data about advertising and want some kind of auditing (can you imagine yet another tracking script that phones home to some consulting company that is charged with keeping Google "honest"?) However, the recent reports that Facebook lied to advertisers shows that the concern is real (if not for Google but at least for some other people). Anyway, what I have learned is that the world of advertising is built on distrust. My understanding of advertising is very limited. It seems like the industry thinks there is value in advertising that does not immediately lead to user action like a purchase. The advertiser gets value out of an ad simply being displayed even if the user has no intention of eating a McDonalds or getting an Uber at this very moment. The problem I can't wrap my head around is how does McDonalds know if an ad display impression is legitimate and how does Google know that all legitimate ad display impressions get counted and paid for without using a third party arbiter (an arbiter is unacceptable to me if I were Google)? I'd love corrections if I made any bad assumptions. Thanks
