I would say because the ones that the artists in the thread are making are being done for fun.
The Original is a cheap corporate styled attempt at some sort of discord Mascot, also the fact that the colors are a back round and aren't a static thing that moves with the wiggles gives it something of an uncanny feel.
Edit : It also kind of hurts that the Trans Flag has some shades that the Modern Corporate Deco style tend to use, and that art style is very off putting once you start noticing it everywhere.
