Honestly to me this claim seems like a stretch. This artist is not the first person to do these kind of high contrast futuristic acid graphics either.
And then things like claiming the double chevrons, symbols in boxes and "aleph" (which is a marathon thing to begin with) next to some text are directly lifted from their designs when they are also common design elements as well, all just seems like someone trying to milk some fame out of this.
And also you famously can't copyright an artsyle.
Edit: after going through the thread and seeing higher quality images, I take all this back. The symbols in the boxes and the aleph text are litterally exactly the same, this is stealing.
A little bit confused by the graph but it seems like he's solidly ahead with most votes counted? So he's secured the win?
