What's different between Google and Apple is that Apple's main revenue source is their software and hardware. Google is built on targeted advertising. You can't pay Apple to target certain users with your ads, aside from promoting an App you made. And that service has fairly basic controls for targeting.
Makes no difference in how they make money point is the same. In addition Apple hardware sales have slowed and is why their services revenue is growing dramatically. Money is in the digital world not hardware and Apple have realized this and thus is why Phil Schiller, Apple’s Head of Worldwide Marketing, took ownership of the App Store ecosystem at the end of 2015. To expand their marketing, aka ad revenue. 2016 they started ASA and since then last I checked in Q1 2020 it represents nearly 25% of their revenue.
Apple is increasingly building their ad network and services, from mostly in app store to all their services. That is there largest growth source. This is exactly why there ASA initiative is taking away third parties ability to collect data. Everything must go through Apple. They are uniquely suited to control every device, app, and downloadable third party apps ability to collect data. They control the entire ecosystem.
Apple targets every user who owns their products. They are collecting your information. They only allow non apple software to collect basic information as Apple wants to control the data for their own benefit. They want to be the one making money off data, not letting Facebook for example collect all of it and send it through their services so they make money while Apple does not. They realize the way forward is digital marketing, not hardware sales.
Same concept as consoles. Lose money per console recoup the losses with software/subscription services.
You don't have to believe me, doubt you will but when I was building an app for both Android and Apple I can tell you which one was far more restrictive with advertising and it came down to ASA. It's good for end users but hurts companies like FB which is why they are so mad about it. Doesn't mean Apple is entirely the good guy. They are just hoarding it instead of everyone hoarding it. A better alternative I'd say because after going through Google Analytics it's rather eye opening how sophisticated that part of the industry has become. Only good thing about Apple, well not true they tell the government to bugger off and that makes me happy.
I do appreciate what they are doing but that doesn't mean they just simply leave money on the table.
Though editing this now to realize this is probably going to get off topic. So I guess to summarize to prevent derailing, Apple aren't the good guys but they are certainly a step ahead of Google in this department and I am glad they lead this more restrictive less identifiable advertising model that Google is now following, as Google Analytics is far to widespread(even on Apple) and no company should have this much control. Can't wait for April to roll around fast enough so these changes come into effect.
