Collecting data about what you did is not necessarily spying. If a game keeps tracks of my wins. That's not spying even though it's collecting data on what I did.

My point is that it's collecting way more data than the single bit it needs in order to tell "yes this ad has been seen, increment the counter".

It's not just about telling if an ad has been seen, but what a user does on your site after clicking on the ad. Do they immediately bounce? Do they buy something?

You want to be able to see that you are actually getting a positive return from the money you are spending on ads.

It’s still spying even if there’s a rational reason for it.
