It does not matter this was said by a member of a unique subgenre of ambulance-chasing-like attorneys: this is the exactly correct question
There is a question as to how much of this sycophancy was intentionally built in; I think there is an additional effect that might be hard for them to remove which is that it is learning from human conversations on the web and those tend to be sycophantic by nature. People are trying to be pleasant with each other (sometimes!) and empathizing with each other and so I think the natural training bias will be towards that kind of behavior. But then the question is why or how they prevent it from trolling and "greater internet fuckwad" behaviour, which is also common on the internet.
