GP proposed the site should solve the problem once at the source, and everyone benefits. You counter-proposed that every individual reader should take manual action on every headline they see. That's a lot of redundant wasted effort across the userbase.
To continue your analogy, that would be like if Gmail got rid of spam filters, and then told people to stop complaining endlessly and manually copy every email they get into SpamGPT to ask if it's spam or not.
