"She hates people to break their word."

[Odessa Dawn]

"While you might think that this is the arena in which we would be LEAST likely to violate our word and fail to keep our commitments, it seems to be the place where these lapses are most likely to show up, perhaps because for many of us it is easy to over-commit in order to accommodate our partner, or to agree to something for the wrong reasons, including the desire to avoid a conflict or a feeling of obligation, that can promote a desire to break our word, or for any number of other reasons that lead to a similar outcome."

"break one's word: not to do what one said one would do; not to keep one's promise. (Compare this with keep one's word.) Don't say you'll visit your grandmother if you can't go. She hates people to break their word. If you break your word, she won't trust you again."

While I was looking for the meaning of "to break your word," I came across the above statement in which the preposition to made me confused since I am not accustomed to using it over here. I prefer the pronoun who over the preposition to in that sentence.

Also, I have checked the below site in which the verb hate can be followed by either gerund or infinitive but not object+ infinitive.

"She hates people to break their word" sounds slightly unnatural. "She hates people breaking their word" is more natural and preserves the meaning that what she hates is the idea of breaking one's word, not the people who do so.

But I think your "She hates people who break their word" is the most natural and best. A strict logician might argue that this usage transfers the hatred from the word-breaking itself to the people who do it, but I think in practice nobody would be bothered or confused by this.
