I think the concern is that people who work in aviation (related to a nations logistics) have more attention and exposure to/from foreign governments
In addition, it is reported that certain company employees were for a long time obstructing the Defence Forces in organizing air and ground defense of the airport.
that sounds pretty clear to me
Its a little hard to imagine you are that incompetent that you start arguing with the damn military. They don't usually have a problem taking over operations of whatever object. That sounds like they decided to get into a argument about airport operations details with the military during a crisis. What motivation could you have to do that?
Also, trying to make use of insurance, particularly on transportation equipment, that could be used for whatever (lets say evacuations), during a time of war, is extremely grimy. It's obvious that those kinds of things get quickly nationalized and very important during a crisis because it can move people and supplies.
