This new baboon set of .gifs is really popular.
However, you can see a
professional artist created these .gifs.
In my opinion, that artist should be profiting from each time we use this .gif. Imagine if your content was being used by a lot of people in expressive ways, but you don't profit from it. Additionally, this artist is likely unaware that we are even using his/her content en masse.
Another thing to think about... is ATRL somehow profiting from our usage of this .gif? Is that grounds for a lawsuit?
