This is airport security in Israel. It's not security theater. It's the real deal. There is something in this story that is missing. You may not know what it is, but those people are really good at their jobs. Was that really your laptop? Were all the files on it really yours? Were you really just there as a SW engineer? Did you really tell them the truth to all 20 questions?
You've claimed to spend time in the country. You know how it works. The people in security make good money and have access to tons of resources ... they don't want your laptop for fun or a side hustle. If you have a grievance against the Israeli government, there is due process there just like in the US. It works as well there as it does in the US. File a suit... the courts will sort this out. (Edit: You also would have received a claim ticket for confiscated property, just like in many US jurisdictions. Something is missing from this story.)
Publicity just makes you look like you are acting in bad faith.
