Apple is again going where Google (the world's largest ad company) cannot follow: 100% user privacy.

They really hammered in the fact that every bit is going to be either fully local or publicly auditable to be private.

There's no way Google can follow, they need the data for their ad modeling. Even if they anonymise it, they still want it.

It's the potential for the model. Everyone else is hoovering the internet to model everything and Apple is sticking with their privacy message and saying 'how can I model your stuff to help you.'

That's tangibly different.
