Imagine buying ad space on their platforms, but instead of writing copy and providing images, you simply give it your website.
Then they generate unique copy and images for each user (or hyper-targeted bucket of users), tailored to what would make them click. All continuously A/B tested.
I'm imagining it, and it'd at best be the same as if you gave your website to an ad sales agent without any instructions as to what your actual product or target audience is. At worst it'd be writing copy that is fully fabricated, doesn't match your brand language, and opens you up for false advertising claims.
