A hypothetical guy works at a hypothetical startup that publishes a lot of blog posts, and he's not the greatest writer, so he uses a hypothetical service that does AI-based editing for him. He loves the service and recommends it to everyone. The startup folds and he goes to work at a different company and that company has a professional copy editor on the payroll so he doesn't need to use the service anymore.

He's churned, but he hasn't rejected the service. He just doesn't need it anymore because his circumstances have changed. If he needs the service it offered, he could presumably re-subscribe to it later.
