The problem is that the way the medium works is that the only way to post something for someone else to see utilizing the wildly adopted protocols (http(s)/html/etc) is to have the item downloaded and copied. The attitude is very much like if someone performed a song, and then got upset that people could remember the song in their heads ("You owe me everything you recall the tune from memory or sing it to yourself in the shower"). This is just how the brain works.
