No advice is perfect for everyone, therefore never give advice? That'd be a pretty terrible idea.
The question is how many people the advice would be useful to vs how many it would harm, and to what degree. Framing it otherwise just inflicts a massive loss of utility on all the people who would have benefited from it - i.e. you'd be choosing a world with more misery to live in.
