I am in favor of severely limiting both copyright and advertising, but for the benefit of everyone, not just for the benefit of a few "AI" companies.

And you will not get it. As the AI pump money into lawyers and politicians - they will be the ones profiting from copyright. Total regulatory capture as US AI companies make it illegal to train AI on their output.

The answer is to simply pay for stuff.

There is no viable model where "have stuff but not pay for it" works out.
