It doesn't matter if it's accurate or not, such judgements are made by most people every day. Someone who was professionally formed somewhere has a higher probability of ties to them later on. Being intelligence services this might be even more true.
In today's political climate where people around the world see Israel judging (and sentencing, and carrying out the punishment) every Palestinian as terrorists, I think this wide brush of judging Israelis on their ties with the IDF is probably widely accepted as "only fair". When it comes to Unit 8200 the implications are even stronger.
But I don't get the US public school system reference. You have to start with a baseline and if you see a private Ivy League school on someone's CV and a random public school on someone else's I'm sure you'll probably make the obvious assumption about which one is better, even if sometimes the obvious is wrong.
