People generate all of the data going into the system and then the middle-men (OpenAI, Microsoft, Google, Big Tech middle-man of the week) reap a disproportinate centralized benefit. That causes a bigger problem than the so-called rent-seeking behavior of copyright holders in this case, as this has the net effect of leveraging human creativity, etc. to devalue it and continue the erosion of the middle class.
Bad things happen when you let middlemen get the upper hand, like the American health care system, or big finance disconnected from the real economy. I'll vote against the middleman every time in favor of the original value creator, because society goes down the toliet when middlemen win.
