I mean they prey on clients. Not financially but emotionally. It could go several ways, but I would say the big one is that they have vulnerable clients, they see themselves as The Ones to help them, the client gets dependent on them, etc. They feed off the client's adoration and dependency and it is entirely possible that they then play games with the client - offering some kind of special treatment or something the client values and then withdrawing it.

I am not saying every therapist does this, and I am not saying those therapists who do are conscious of why or even that they're doing this. Nor am I saying that a therapist who has allowed some privilege or behavior and then withdrawn it is doing this. But I definitely think there are therapists out there who are drawn to the vulnerable in a bad way.
