I was actually curious about all of them as I've been both buy and sell side. But I'd like to dig further on the buy side.

I've seen what happens with the consciously accepting route--not pretty. Furthers distrust of a channel many already have inherent concerns and varying degrees of understanding, which is a dangerous combo.

Giving the data is what I suspect many will do unless they have sufficient resources for said legal team and technology, or care a great deal about leaking data.

The last option is interesting. So I've used Snowplow (was actually an early user that sponsored them adding UTM remapping). I'm curious how you approached using it as a poor-man's ad server with Cloudfront which I'm less familiar with. Are there any technical write-ups you could point me to?
