I have been a Listener solver, on-and-off, for many years and I know about the statistics and so on, but as I said before I do not object to hints. It's not like, for example, cheating in an exam and getting a degree you don't deserve. Furthermore, knowing that some people are getting a little help doesn't make the puzzle harder to solve for me.
There is also the consideration, which I think has been mentioned before, that giving a few hints to inexperienced solvers might help them to gain a better understanding of the way things work so that they eventually become more confident and can manage on their own.
As for threatening to withdraw the puzzle, I fail to see what good would be achieved by that course of action.
