Can someone explain why livestreamers can claim their stream as their own original content, but reuploaders can't? I mean, someone who livestreams a game is primarily showing off the artwork and level design and everything put in by the game company. There's like 90% derived content plus 10% original. A reuploader does exactly that: take 90% of their content from elsewhere (the livestreamer) and add 10% (good editing).
I understand that all this is in everybody's benefit: a game company likes livestreamers because it helps market their game, and a livestreamer likes reuploaders because it helps market their stream. So the amount of cease-and-desists going about is low. But still, why does the livestreamer get to own the content, and not the reuploader? I really don't see the difference to be frank.
