This piece links to a Futurism article[0], which in turn links to "an incredibly defensive statement"[1] from the ad agency.
> “For seven weeks, we hardly slept, with up to 10 of our in-house AI and post specialists at The Gardening Club [our in-house AI engine] working in lockstep with the directors,” Sweetshop’s CEO wrote.
(Sounds more like sweatshop than sweetshop, but I digress.)
However, that "defensive statement" link is broken, and I see no sign of it on the linked site, but I did find this older lamentation[2] from The Sweetshop regarding AI, or more specifically regarding the attitude that AI should allow you to cut costs and fire people.
> Being asked to cut 20–30% of creative costs and labour under the banner of ‘AI’ is unimaginative at best, and corrosive at worst. It drains the value of human creativity and concentrates it in fewer and fewer hands, hollowing out the very industry it claims to improve.
