As someone who's also worked in Israel and worked with the tech scene there firsthand too I dispute this quite strongly. Israel has mandatory conscription that is rather difficult to get out of, and given their precarious situation in the Middle East I'm not entirely sure I'd blame them. As a result, the entire country spends their lives between the ages of 18-20 working in the military in some capacity, meaning that you can very easily make a case of 'military links' for any industry. The milk you drink from your hotel in Tel Aviv? Owned by a former IDF commando and run by employees who almost entirely all served in the IDF. Tech is no exception, and to just say that because there are IDF graduates who staff the myriad companies in the tech industry so now it's somehow 'controlled by the IDF' is utterly preposterous. Is Tnuva suddenly an IDF controlled subsidiary? If I buy milk from Tnuva, am I suddenly now supporting the IDF and the government?
Your assertion that the IDF, Israeli government, and cybersecurity industry are effectively one unit is also bizarre to say the least, considering that they're entirely private companies who refuse to take orders from the government and have raised a stink about attempts to do so on more than one occasion. Your comment becomes more and more laughable when you assert that these companies are 'essentially subsidiaries' of the IDF. Please, you're fooling nobody. The issue here is about control - whether these companies advance Israeli foreign policy goals at the explicit direction of the government. Yet even a quick look at the clients of many of these groups shows this to be not the case.
