It makes me terribly sad. that's the flaw with all arts, whether visual, musical or dance. People think they can copyright an idea. It makes any art really hard, especially music. Like people try to copyright certain patterns of notes.
Like yeah, you can try and copyright something, just don't expect someone to pay you $25 dollars just so they can draw what they want. Having an idea doesn't make it yours, because someone can have the same exact idea and have never met your CS or even know who you are.
