Someone is presumably making a handsome living by lying for the rich, so at least one person wants this. And there are people paying for this service, so clearly there are people who want to live in this kind of world.

It doesn't matter that this problem has existed forever. So has murder. Are you arguing that we shouldn't care about people murdering each other because it's a timeless problem? I assume no.

It's not tricky at all when someone knowingly, intentionally pushes fake content at scale to sway public opinion. That's an unconscionable act with very clear and dark intentions. That shouldn't be "tricky" to assess, because we know very clearly that what they are doing is absolutely, unequivocally, wrong.
