It's never been a matter of ads, it's always been about
tracking. Ads just happen to be the vector in which tracking is default included, as is well, other tracking scripts around the web and via mobile SDKs.
What Apple's doing here is trying to undercut in a serious way the ability for everyone to be able to do the kind of granular tracking we have today all over the place.
I'm not shocked they're building / expanding an ads division. The real key is this: will their ads be served up with the kind of granular, identifiable tracking we have today? My gut feeling is no, it won't be[0]
[0]: As an aside, I want to note the following:
When I say tracking or speak of it in this context, I do not mean simple metrics, like how many page views did this get compared to Ad B? That is the kind of, well, tracking, that can be done in a way that isn't privacy invasive (and should never be invasive), akin to A/B testing. Technically, error logs are a form of tracking, if we want to be pedantic. Instead, I to point out that I'm talking about granular tracking data that can be used to identify a person or granular set of data that can sort people into unique groups that then make it easy to identify them. The real quandary here of course, is that in some cases Facebook, Amazon, Google and others have enough data to actually be able to say oh hey, this is no_wizard, not some other person. Thats a huge part of this problem, however, its also not always the case that they can harvest enough data to be able to do that. The other, often overlooked issue by many (particularly those that don't follow this sort of thing. Not likely your average HN reader but probably most people you know, is that they also have the heustristic data that confidently sort people into little groups, and they are constantly continuing this narrowing. So instead of saying hey, this is no_wizard they can say, well, looks like someone who identifies as no_wizard believes in these causes, has these purchasing habits, and has seen these ads, along with x people from Y area, lets put them in Z group
I know people get upset (ever so rightly) about being personally tracked, but both issues need to be systemically addressed. Its not about ads, its about what ads became, and through that we now have this kind of detailed tracking all over the place, from mobile SDKs to CLIs to most popular websites.
I would welcome an Apple Ads platform that went against all this and could prove it
