I dunno about revolving. The pay in the private sector is very good. Tons of folks who worked in the IDF end up at tech companies for two reasons:

(1) almost everyone goes through the IDF thanks to mandatory service

(2) if you have aptitude you end up in the signal Corp, who are good at what they do.

I wouldn't call this a conspiracy, and the parents speculation is very thin. If the author got this from the IDF they almost certainly wouldn't be publishing; breaking that kind of confidentiality can end really badly
