I wouldnt say all copyright is bad, but rather copyright law as it is is rife with abuse and bad actors. Big corporations use it like a hammer, and small creators arent able to go up against big corporations if they steal copyrighted work. And copyright/patent trolls are able to shut down anything and everything no questions asked.

There needs to be some way for individuals to have some protections for their work, but the current system aint it. (And this is before AI)
