I used to not even think about this and I would just do it. However now I'm wondering if I'm giving away my trade secrets to rigging, mesh deform, setup, graph technique and animation technique. Big companies go to war to protect trade secrets and if you leak them they can sue you.
Is this the correct etiquette for dealing with clients or do they expect to get my editor files? I feel it's in my best interest to just give them the export JSON or .Skel file and the image atlases. If they can reverse engineer it from those files than I guess that is what it is.
I feel if I were to give away my editor files or if they were to request them I would ask for a big chunk of money. It would be like if a musician gave away their raw music files.
Am I being unreasonable or have I been a fool to give up my editor files? (I haven't done it many times)
