That's fine as long as the targeting is solely based on data that I expressly gave to the organisation that produces the product that the ad is for.

If the ad is based on data that was harvested without my permission from a source that wasn't related in any way to the product then I don't want it targeting me.

And every single targeted ad is of the second type. It's nefarious and I have no issue with the current type of targeting being restricted.
