I think there is also an element of short term vs long term reward. Things that are more likely to be worth paying for often are harder and longer term in some way (like university or even reading a novel) while ad delivered content generally is optimized to be easy to consume, and almost consequentially is very shallow. Because the goal is to keep attention, not to be comprehensive or useful.

So I think there is an argument that ad support, and attention focused platforms in general, do have a negative effect on the content.
