Have you considered that “all that criticism” may come from a relatively homogenous, narrow slice of the market that is not representative of the overall market preference?
I suspect a lot of people who are from a very similar background to those making the criticism and likely share it fail to consider that, because the criticism follows their own preferences and viewing its frequency in the media that they consume as representaive of the market is validating.
EDIT: I want to emphasize that I also share the preference that is expressed in the criticisms being discussed, but I also know that my preferred tone for an AI chatbot would probably be viewed as brusque, condescending, and off-putting by most of the market.
