This is completely false. Large advertising platforms have many A/B tests that show significant differences in consumer behavior between groups that receive different ad treatments.

Ads might be less efficient than some believe, but it's super easy to see that they "work", and advertising platforms do it constantly.

That's comparing one type of ad or channel to another.

But none of them test "no ads" vs "ads".

Some of the A/B tests I have analyzed are exactly "no ads" vs "ads"
