I don't think copyright itself is bad, but the way in which Disney has gotten the government to enforce it is absurd. If I ever release a creative work, I'd make sure to do it in a way where the work is free to share but I would still own the right to produce that work until I am dead. I think that's perfectly reasonable, but copyright in the US today is effectively indefinite and intentionally difficult to make sense of. All you have to do is shove a bunch of other licensed copyrighted material into your work so that only your company can resell that work after the main copyright has expired.
