I can’t answer all your questions now.1. https://fossbytes.com/apple-data-collection-explained/ - The data Apple collects for its ad business
2. Facebook has its appstore on iOS? News to me.
3. I quoted F-droid to show that Appstores can be free as somebody said nothing can be free.
4. Apple's service revenue is not a point of discussion here as I am not debating it.
5. You may be a BA, but until you expand your horizons and know all the facts, you cannot know how a company makes money. Do you know all the revenue streams that Apple has? There may be many that we are not even privy to. Their ad business depends on data collection and that is the reason why it tripled once ATT came into place as it restricted the data on iOS to only Apple. https://www.emarketer.com/content/apple-ad-revenues-skyrocket-amid-its-privacy-changes - Please pay attention to the last paragraph. I am quoting it here:
"Though Apple is reaping the benefits now, the sheer scale of its growth will be hard for antitrust regulators to ignore for too long. Even though its iOS 14.5 changes were made in the name of privacy, regulators are unlikely to take kindly to how much of an advantage they give Apple’s own ad business."
But read my comment again and then compare it to the Forbes link you papered. Remember the difference between information and data and what user profiling is and who does it.
I said Facebook has its own App Store. I didn’t say it was on iOS.
I have been in business sector for the last 30 years and I have co-authored white papers and peer reviewed academic studies within the topics of digital privacy and data governance including international laws. I will have to ignore your suggestion about me widening my horizon. I am not the one who is severely misinformed here. I am trying to inform you respectfully. Please keep it civilized. I am not youngsters like most users here.
