Ehhhhh if kids are paying for it then that's on them. If the guy is on the up and up and just training them I would say no, they just are using the facility that happens to be a private school. Now if he's also pushing the school on kids in the sessions then yeah. But how do you prove that?
I know it happens and have seen it, I've coached both private and public, but sometimes the tin foil hats come out any time a private school is mentioned.
We all know that is a recruiting tool. However, bc they are paying for it, you will never be able to prove that the guy is recruiting other kids. Same thing happens around here and probably about everywhere these days. Someone opens up a training facility. Runs kids through a bunch of cones or ladders, takes there money, calls it training, and then talks to the ones that are good about how great it is to go to his school. They dont do anything that we dont do in our off season program, they only have 1 on 1 or small group sessions that we cant do. You cant tell your kids not to go to such places either or now your the bad guy. Its a PIA.
What if it is? This is not a popular opinion here, but if that school is offering a better academic/athletic option, why shouldn't a kid consider it? I mean, I hate when it happens but at the same time I really can't hold it against a family if they decide to go somewhere else if the situation is better than the one they are currently at.
Now I do realize there are some unscrupulous characters that are taking advantage of kids, but there is also a lot of public school to a different public school scenarios that a transfer would help a kid. If coaches can pick up and leave at any time why shouldn't an athlete be able to?
Also, I use to run camps at our school and invited players from the surrounding area to come to it. I never recruited, hell nobody wanted to come to our place. Instead I used it as a fund raiser to buy stuff for our program. Gave me an extra opportunity to improve my coaching, gave kids from area schools a chance to get to know each other personally (less hate and attitude during the season) and some kids got a lot better than they normally would during the off season. Win Win Win for all.
