[Many People AFK when I Open Public RailJack mission o.O]

Many People AFK join me when I Open Public RailJack mission.. are they also receive affinity and rewards too? and use navigation without my permission on my RailJack even the other squadmates want to little bit farm resource.. I mean, is this my RailJack right? they just hitchhike then AFK... and they do the things they want in my RailJack? I feel offended by their behavior.. I don't want to be selfish but at least do something so we can complete the mission together.. If they are new players, that is understandable..
