Without the revenue by ads you have to pay for the services.To pay you have to register and you are loosing more of your anonymity than through tracking.
You say people are losing more of their anonymity by paying like it’s a definite—it isn’t.
Registering to pay gives an email address, sure, but I make a temporary email address for every service I sign up for, which is a method available to others—whether they know it or not.
There are multiple ways to pay without using your physical address, and even if you did, there are more invasive ways that apps track you, like your location
when using the app—which can be and often is different than your billing address. Apps can also track interactions and browsing history across apps, which registering to pay does not do.
The problem with Apple Tracking Transparency is that the ads will not disappear but ads sold by Apple will be more efficient than those sold by other companies. Since you are only allowed to install apps through the Appstore, Apple knows a lot about you.
Reducing my attack vectors/all of the ways my information can leak down? Sign me up.
Potentially granting the stewardship of my info to one company isn’t perfect, but if I have to do it, giving it to a company who has tangibly demonstrated a greater commitment to user privacy than most others? Even better.
It seems that your understanding of this case isn't in any way superior to the competence of German courts.
If you don’t understand the level of user activity and information that can be gleaned and combined using the IDFA vs. an email address/registration for payment, or how limiting your personal info to a smaller amount of companies that have shown more responsibility with regard to user data vs. a free for all spread that is likely happening without users’ knowledge or consent…then perhaps it is you it is that doesn’t understand the issues at play in this case.
