The number of times I've been attacked over tone growing up tells me that I either had abusive parents, ~~or~~ and that how you say stuff matters a lot. Intonation can also turn a statement into a question or even make it sarcastic. Words come with baggage beyond their meaning, and using a word with negative connotations can turn a compliment into an insult.

In the specific case of clanker vocab leaking into the general population, that's no big deal. Bots are "trained" towards bland, unoffensive, neutral words and expressions; stuff like "indeed", "push the boundaries of", "delve", "navigate the complexities of $topic". Mostly overly verbose discourse markers.

However when speaking in general grounds you're of course correct, since the choice of words does change the meaning. For example, a "please" within a request might not change the core meaning, but it still adds meaning - because it conveys "I believe to be necessary to show you respect".
