Are you telling us there should be a form of copyright for the first person to publish a link on a social media ? And then everybody should thanks this person and forget about the author of the original work ?

HN does not allow to give hat-tips or other Twitter-like credits. Where should they even put that? In the title?

It is: first come-first serve and I don't think you can even mention the OP of this post without scrolling back and looking it up. It doesn't matter much to you and me.

No one cares, how do you know the twitter person did not copy from somewhere else without giving credit?

Or somebody actually managed to find this on their own.
