The issue is that an extremely sensitive negotiation (interviewing and hiring process) is utterly disrupted by their presence, so nobody is in a good position to legally challenge them. If almost ANY non compete is in place, the potential employer is highly likely to make the decision not to bother with the candidate. Proving that it was because of the noncompete is difficult (making it difficult to prove real damages).

They would almost certainly fall apart in court, but the systems they disrupt don’t survive long enough to move them into court.
