Groni, any component of a file that is posted here can be used in another file, historically. Once you post a model that uses a sound profile, blade, prop, battery, engine (those 2 are defined in the RF editor), etc., it's available for others to use. How am I to know whether a battery I picked is one you designed? It's not delineated in the editor like that. The only unacceptable thing to do is for someone to post an EA when he didn't build the 3D model. That's the way it's always been. Otherwise, a sound profile is a sound profile, and if I have it available, I may use it. If you don't want others to use it, don't post it.
