Totally agree, but a dozen apples and a bushel of apples are both a bunch of apples. Scale doesn't really change what I'm saying.
creator profit & corpo profit = good <- this is where most of fanart is
If I understand your point correctly, it's not the profit from the fan art that the creator gets, it's that the fan art drives profit of their original artwork, right? Because we both agree that profiting from someone else' IP is illegal, right?
no creator profit & corpo profit = bad <- this is where most of the modding for popular and live games like WoW and Minecraft is
As well as any fan art itself, legally speaking, right?
