What the difference between Meta's tracking pixel and Apple's IDFA?
> Starting in iOS 14.5, iPadOS 14.5, and tvOS 14.5, users are prompted to decide whether to opt-in or out of IDFA sharing before apps can query it. This choice can be altered in Settings.[2][3] In May, 2021, Verizon-owned advertisement analytics company Flurry Analytics reported that 96% of US users opted out of IDFA sharing.[4]
And since you brought out the opt-out option, one can also block Facebook's trackers through uBlock and/or DNS filters.
The defaults are what matters. From the same Wikipedia article,
> Users can opt-out of IDFA via the "Limit Ad Tracking" (LAT) setting (and an estimated 20% do).
80% users never change the defaults.
Apple’s own apps don’t need to display the prompt because as per their privacy policy they don’t collect or use information for tracking purposes (which is also visible in the privacy labels of their apps in the App Store).
This is the privacy policy [0] of an example of their app, Apple News. I quote:
"Advertising
In order to deliver great content to you from leading publishers, Apple News is ad supported. If the Personalized Ads setting is on, Apple’s advertising platform may use information about your account, the topics and categories of stories you read, and publications you follow, subscribe to, or turn on notifications for to serve ads that are more relevant to you. We may also use information about your subscriptions to personalize your ads on the App Store."
In this case, you're referring to "Data Linked to You". "Data Linked to You" is based on the account you used to sign in to the News app + your activity within the news app - to create suggestions within the News app.
This does not allow Apple to track you from the News app e.g. access the IDFA of the device, sharing it with third parties or other apps.
They claim they do not share this data with other third parties but they sure as hell use it for their own advertising ecosystem.
Trust me bro.
If it's so clear that users don't want to be tracked online, why don't we just ban it altogether? It would solve a lot of problems.
Apple doing it unilaterally on their platform might invite anti-trust concerns.
There has been a setting to turn the IDFA completely off for well over a decade.
Previously, apps on iOS or Android had access to the unchanging hardware ID number of the device.
> Apple notes that it will be phasing out access to the unique device identifier, or UDID, on iOS devices such as iPhones and iPads.
This is a big deal, especially for any mobile ad networks, game networks or any app which relies on the UDID to identify users.
https://techcrunch.com/2011/08/19/apple-ios-5-phasing-out-ud...
Apple replaced the hardware ID with a random number (the IDFA) that could be reset by the user at any time, or turned off completely.
Google eventually followed suit, although any app that received the. READ_PHONE_STATE permission was immune to the protections.
> READ_PHONE_STATE is one of the Android permissions categorized as dangerous. This is because it “allows read only access to phone state, including the phone number of the device, current cellular network information, the status of any ongoing calls, and a list of any Phone Accounts registered on the device”.
... it is often requested and misused by other types of applications that do not have any reason for needing it, including malware.

The recent changes at Apple were to make the IDFA opt out by default and to track the permission to use it per app instead of per device.
Apple doesn’t.
It’s really that simple.
Displaying an ad next to search results based on the search query for example is similarly benign.
Enough with carrying water for a megacorp that makes money from selling advertising services.
On the other hand, I very much await sideloading to be forced out of Apple by the EU.
This is true, but many criticisms are valid. Apple News is user-tracking adware that cannot be uninstalled on MacOS. You cannot install an app on any of the iDevices without telling Apple. You cannot get your GPS location on an iDevice without telling Apple. Apple is spending considerable resources growing their ad business, so expect this to grow worse over time; and combined with Apple's inclination to deny user control, there is no way to opt out without opting out entirely of iDevices.
So Apple's privacy perspective is way better than Android's. Could it be better? Of course, and I'm fine with trying to pressure them to do more for protecting our privacy, but between the 2, it's not even close, Apple is WAY more private with your data than Google will ever be.
The difference is you can avoid the tracking easily. This is a direct result of prioritizing user control. You can install apps without telling anybody, you can get your GPS location without telling anybody, and so on. Apple, by denying user control, makes privacy worse for users who care, and it will only get worse as Apple ramps up its services business.
Many of the same people who see no issue with this mock and insult Microsoft for promoting Edge etc., in Windows. And will pretzel themselves into explaining how "that's different".
Billboards still require tracking. If you had the option of putting a billboard up in 1 of 2 neighborhoods and it would get 10k impressions in either location which one would you choose? The optimal strategy is not to pick randomly. The optimal strategy is to predict the conversion rate of both locations. In order to do that you need to investigate who is likely to see your billboard and learn about their interests to see if they would be likely to be interested.
I don't doubt that billboards are placed with some careful thought, but tracking is certainly not "required" - some aggregate stats about an area should work, especially as there isn't much feedback on who saw the billboard and bought a product etc.
What billboard is tracking individuals?
Billboards that identify car types are still legal AFAIK.

I haven't seen a billboard that would follow me around before. Placing them at popular location depends on existing data (or often just plain-ass thinking, like obviously a hub in the middle of the town will have more people see it compared to the middle of nowhere), and only very very indirectly generates any sort of new data (e.g. if you only place a single ad in a specific place and can correlate that placement with an increase in product sales.. but that is thoroughly unrealistic and I only write it to be nitpicky with myself).
I've never seen a png file follow me around either. It's the people who are selling the advertising space that are doing the tracking. They want to show how valuable of a location they can offer you.
Facebook on the other hand, creates a grand central repository of everything there is to know about you and sells it to whoever wants to pay. Just like Google.
