As a sometimes designer, i don’t think there’s any distinction between punishing the ad and the company. The company bought the ad, probably directed its creation, and decided what its criteria was for success. 1-star away as far as I’m concerned.
I think they mean they leave a 1 star review on the app that was displaying the ad, who probably didn't directly do any of that.
They did work with a bad ad network though so it's a valid enough reason to complain imo.
I feel the same way about newsletters.
“Hey you bought socks that one time! Want more socks??” -> Unsubscribe.
“Hey it’s your weekly sock news! What’s new in socks!” -> But I unsubscribed! Haha no, you only unsubscribed from the “product releases” list. Not the “weekly news” list or our 10 other fabulous mailing lists!
-> Report all emails from this domain as spam. May god have mercy on your soul, cute socks.
