> affects their own word choice.

exactly. in the same way that printed books affected word choice, so did the radio.

I can't remember any radio determining words or adjusting grammar of the person speaking through it. Neither can I recall there has ever been a moveable type press, laser printer, or inkjet which bastardised the words of authors.

These were mediums _through_ which communication happened. Language models, large or small, are not any such medium.
