For people who are already networking as much as they can, working hard on their personal brand, etc. and still finding it doesn't seem to be working out for them (probably most people), you're telling them to do what they are already doing and that it will make them more successful.
That's isn't useful. It's non-actionable advice, and empirically wrong in their experience.
For people in that situation, your advice is pointing them in the wrong direction, and that's what I read into "misinformation" in the GP comment.
