What is the deal with the "stop stealing" on the gallery?

I'm so glad to know there are other simmers who uses the Gallery as a back up...Personally when I make Sims and builds .. I only upload the ones I can't do without in my game and my favs to the Gallery just for back ups and when they get downloaded its just a bonus for me..

This has actually paid off cause there was a time a particular Dlc or patch Came out that caused mad lag and we were advised to clear out our tray folder /library to solve the problem...Since then I got even more serious with making the Gallery my back up save.

Meanwhile I actually kinda understand the no stealing concept..not that I have ever used the hash tag before (lol what do I even have to be stolen ) and most times when I download other people's creation I always end up modifying it to my taste and when I re-upload I just write original design not by me (most times I don't even know the original author's name but thank God for EA's Credit system now) and I state what I modified (i.e interior..redesigning..etc)
