This is a pretty shallow (and repetitive) argument on multiple threads btw. You are implying that college coaches have no integrity here. I think that is unfair.
The coaches on the women's side studied this for 4+ years considering different dates and strategies to slow down recruiting. Many people wanted July 1 of senior year...coaches knew it wouldn't have enough support. That said....the September 1st date was all about having a full summer to evaluate and play in peace (no phone calls or texts); having August for families and coaches to unwind from a busy summer and having the fall to visit schools when teams are on campus and school is in session so PSA's could see a full day in the life of a player. Important information for better decision making on both sides of the equation.
Coaches wanting kids to come to their camp has not changed in 10-15 years. If you ask college coaches (on the women's side at least), they will tell you the Sept 1st legislation has impacted their camp numbers negatively...but they do not care because they think the impact of the rule has been good so far.
September 1 has not negatively impacted their camp numbers. There are just as many 8th and 9th graders attending as ever and the numbers for 10th graders are much higher because they are not committed as they would have been in the past.
No one is arguing that the overall impact of the change has been good. But lacrosse arguing over 2 months is silly. No one is stopping the kids from visiting schools now that they are interested in. Just because they can't talk to the coaches they can certainly visit the school, take tours, even sit in classes. That argument just doesn't fly. Coaches have been watching current 2021s for 3 years. They don't need 4 more tournaments to figure it out. Most coaches were watching 2021's last summer. Many coaches will have moved on to watching 2022s this summer. Many were watching 2022s already last summer.
