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

I don't consider anything created in this game as stealing because it is owned solely by EA. However I do find it to be disrespectful when a player download & changes few things or not and than re-uploads without crediting or not even mentioning the original creator whom probably spent hours or even days perfecting their creative build. It is my understanding that now the gallery will mention the original creator even though the player that is re-uploading don't do so, but at the beginning of the release of the The Sims 4 game it wasn't the case. If a player didn't mentioned the original creator nobody would have known unless it was pointed out. At the end it is all about respecting one another and not doing to others what you don't want to be done on to you.
