If something immediately drops off the front page/is hidden, it's the same is it never being posted. Hard to interact with something which doesn't seem to exist.
There's a public log of killed stories, with clickable link intact to the source, available inline to anyone who cares. If it was never posted at all, there would be nothing. Killing it removes the chance for traction and buzz.
If you don't have a hidden motivation (ie, financial or political interest) in driving views to your link, it's not very painful if it doesn't gain traction without being killed, nobody was going to comment anyway.
If there is a hidden motivation to the link, like the torrent of web3 sewage, or information space poisoning actions by foreign powers, as a user I'm actively happy to see them killed.
