That's a weird comparison because it's a mechanical and deterministic task. Bad autocomplete is just a bad algorithm. As far as I know, (word) artists are usually following the grammatical (or orthographic) rules of their target language by default, and if they want to do something else they would disable that. But it's not really a question of style if you misspell certain words. Your example would be like letting a Thesaurus suggest different words in every sentence.
