The conglomerates who already have a bunch of IP they can feed into those systems, who can afford to purchase or through brute force (ie cheaply employed artists) create new works using their already massive amounts of capital. These are the entities that will have complete and total control over the best versions of the tools that artists say will bring about their doom. You better fucking believe they'll have their own licensing system too.
Copyright is a prison built for artists by big business, successfully marketed to artists as being a home.
